Microelectronics Colloquium

Material Engineering for Stability Improvement of Perovskite Solar Cells

C.P. Wong
Georgia Tech

Organolead halide perovskites have recently emerged as a fascinating light harvesting material that combines the advantages of simple fabrication process and excellent electronic properties. The power conversion efficiency (PCE) of perovskite solar cells (PSCs) has been rapidly improved from 3.8% to 23.3% within the past several years. In contrast to the stunning rise in efficiency, the instability of the PSCs is its Achilles’ heel. The instability issue of the whole device originates not only from the perovskite layer itself, but also from the use of doped organic charge transport materials, such as spiro-MeOTAD. This talk is to provide material strategies to improve the stability of the organolead halide perovskite materials as well as other functional layers in PSCs. To improve the air-stability of perovskite films prepared from two-step sequential deposition by simultaneously eliminating PbI2 residue and improving the crystallinity of the perovskite films. We developed PbI2 thin films with nano-pores and tunable crystal sizes, which enabled full conversion of PbI2 to MAPbI3. A large perovskite crystalline domains, and that the impurity-free, lead to reduced trap states and improved air-stability of the perovskite thin films. The second part of my talk is devoted to improve the stability of the entire PSC device by developing a solution-processed NiOx hole-transport layer, as the hygroscopic nature of the NiOx film suppresses the diffusion of water molecules to the perovskite, and it is also insusceptible to heat. As a result, the PSCs with a structure of FTO / TiO2 / Perovskite / NiOx / Au demonstrated remarkable air-stability and thermal stability. By further modifying of the NiOx / metal interface by CuSCN, we further realized high-efficiency PSCs with excellent air stability, exhibiting nearly no efficiency degradation after exposed to air for 4 months. Furthermore, the ion migration-induced instability issue through incorporating extrinsic alkali cations (i.e., Rb+, K+, Na+, or Li+) into the perovskite. The size-dependent interstitial occupancy of the extrinsic alkali cations in the perovskite lattice was proposed and verified for the first time through density functional theory (DFT) calculations. Such interstitial doping method suppressed I- ion migration in the bulk of perovskites, thus resulting in reduced I-V hysteresis of the PSCs, weakened poling effects and improved photo stability of wide-bandgap mixed-halide perovskites.

Wideband phased arrays for future wireless communication terminals, Daniele Cavallo (TS group)

Wireless data traffic will grow exponentially in the next years, due to the proliferation of user terminals and bandwidth-greedy applications. To address this demand, the next generations of mobile communication (5G and beyond) will have to shift the operation to higher frequencies, especially to millimetre-wave (mmWave) spectrum (30-300 GHz), that can provide extremely high-speed data links. To enable mm-wave wireless communication, mobile terminals such as smartphones will need phased arrays antennas, able to radiate or receive greater power in specific directions that can be dynamically steered electronically. However, to cover the different 5G mm-wave bands simultaneously (28, 39, 60 GHz, …) and to achieve total angular coverage, too many of such antennas should be on the same device: the main bottleneck is the insufficient space available to place all antenna modules. Therefore, I propose to investigate novel phased array antenna solutions with very large angular coverage and ultra-wide frequency bandwidth, to massively reduce the overall space occupation of handset antennas and overcome the current limitations of mobile terminal antenna development.

Towards smart organs-on-chip, Massimo Mastrangeli (ECTM Group)

Organs-on-chip are microfluidic systems that enable dynamic tissue co-cultures under physiologically realistic conditions. OOCs are helping innovating the drug screening process and gaining new fundamental insights in human physiology. In this talk, after a summary of my past research journey, I will describe how the ECTM group at TU Delft is envisioning the use microfabrication and materials science to embed real-time sensing and actuation in innovative and scalable OOC platforms.

Emerging electronic materials: from lab to fab, Sten Vollebregt (ECTM group)

Due to their nm-size features and often unique physical properties nanomaterials, like nanotubes and 2D materials, can potentially outperform classical materials or even provide functionality which cannot be obtained otherwise. Because of this, these nanomaterials hold many promises for the next generation of devices for sensing & communication and health & wellbeing.

Unfortunately, many promising applications of nanomaterials never reach sufficient maturity to be implemented in actual products. This is mostly because the interest in the academic community reduces once the initial properties have been demonstrated, while the risk for industrialization is still too high for most companies to start their own R&D activities. My goal is to bridge these two worlds by investigating the integration of novel nanomaterials in semiconductor technology and demonstrating the scalability of novel sensing devices. In this talk, I will give examples on how carbon nanotubes, graphene and other emerging nanomaterials can be used in the next generation of sensing devices.

Reducing Switching Artifacts in Chopper Amplifiers

Yoshinori Kusuda


Chopping is a technique with which amplifier offset can be reduced to sub-μV levels, at the expense of reduced signal bandwidth due to chopping artifacts such as up-modulated ripple and glitches. In this talk, some circuit techniques to reduce such artifacts are proposed.These circuit techniques have been used in three commercially-available operational amplifiers, whose design and measured performance will be discussed. Lastly, some of the challenges associated in testing low-offset amplifiers in mass-production will be discussed..


Yoshinori Kusuda received the B.S. degree in electrical and electronic engineering in 2002, and M.S. degree in PhysicalElectronics in 2004, both from Tokyo Institute of Technology. Upon his graduation in 2004, he joined the Japan DesignCenter of Analog Devices (ADI) as an IC design engineer. He is currently based in San Jose, CA, U.S.A., working for the Linear and Precision Technology Group of ADI. The focus of his work is on precision CMOS analog designs, including stand-alone amplifiers and application specific mixed-signal products. This has resulted in presentations and papers at IEEE conferences and journals, as well as nine issued U.S. patents. Since August2015, he has been a guest researcher at the ElectronicInstrumentation Laboratory of the TU Delft.

Front-End ASICs for 3-D Ultrasound: From Beamforming to Digitization

12:00 - 12:15 Introductory presentation
12:30 - 13:30 Public defense
13:45 - 14:00 Diploma ceremony
Address: Senaatszaal of the Aula Congress Center

This thesis describes the analysis, design and evaluation of front-end application-specific integrated circuits (ASICs) for 3-D medical ultrasound imaging, with the focus on the receive electronics. They are specifically designed for next-generation miniature 3-D ultrasound devices, such as transesophageal echocardiography (TEE), intracardiac echocardiography (ICE) and intravascular ultrasound (IVUS) probes. These probes, equipped with 2-D array transducers and thus the capability of volumetric visualization, are crucial for both accurate diagnosis and therapy guidance of cardiovascular diseases. However, their stringent size constraints, as well as the limited power budget, increase the difficulty in integrating in-probe electronics. The mismatch between the increasing number of transducer elements and the limited cable count that can be accommodated, also makes it challenging to acquire data from these probes. Front-end ASICs that are optimized in both system architecture and circuit-level implementation are proposed in this thesis to tackle these problems.
The techniques described in this thesis have been applied in several prototype realizations, including one LNA test chip, one PVDF readout IC, two analog beamforming ASICs and one ASIC with on-chip digitization and datalinks. All prototypes have been evaluated both electrically and acoustically. The LNA test chip achieved a noise-efficiency factor (NEF) that is 2.5 × better than the state-of-the-art. One of the analog beamforming ASIC achieved a 0.27 mW/element power efficiency with a compact layout matched to a 150 µm element pitch. This is the highest power-efficiency and smallest pitch to date, in comparison with state-of-the-art ultrasound front-end ASICs. The ASIC with integrated beamforming ADC consumed only 0.91 mW/element within the same element area. A comparison with previous digitization solutions for 3-D ultrasound shows that this work achieved a 10 × improvement in power-efficiency, as well as a 3.3 × improvement in integration density.

On the Relationship between Nyquist Rate and Healthcare: Silicon Systems to Close the Sub-Sampling Gap in Health Screening and Monitoring

Amin Arbabian, PhD (Stanford University)

Advances in healthcare technologies have mainly focused on therapeutics, interventional procedures, and “late-stage” diagnostics. These steps have undergone significant improvements, leading to higher survival rates and enhancements in quality of life. Nevertheless, current trends are unsustainable due to the inadequate outcomes on specific critical diseases and skyrocketing national healthcare costs. An important example is cancer, where mortality rates have not seen major improvements, even with the tremendous technological advances in diagnostic imaging tools over the last four decades.

In this talk I will outline our efforts in better marrying technology and healthcare with new systems that 1) enable continuous “Nyquist” imaging and screening to enable preventive/predictive care, and 2) introduce smart implants for precision monitoring and closed-loop therapies. Preventive screening through continuous monitoring has the potential to fundamentally revamp our understanding of disease as well as targeted therapy. Today, the human body is monitored infrequently, perhaps on an annual basis and with a low “resolution”. This is in contrast with advanced electronic systems (many of which our community designs and ships), which are frequently monitored and calibrated. I will summarize a few example projects that aim to address these issues, including portable, semiconductor-based, “Tricorder” imaging systems, ultrasound-powered implantable devices that can measure, detect, and act upon local physiological changes through closed-loop neuromodulation or “electroceuticals”, and finally our new investigation of a noninvasive methods of neuromodulation based on ultrasonic excitation.

Amin Arbabian received his Ph.D. degree in EECS from UC Berkeley in 2011 and in 2012 joined Stanford University, as an Assistant Professor of Electrical Engineering. His research interests are in mm-wave and high-frequency circuits and systems, imaging technologies, and ultra-low power sensors and implantable devices. Prof. Arbabian currently serves on the steering committee of RFIC, the technical program committees of RFIC and ESSCIRC, and as associate editor of the IEEE Solid-State Circuits Letters (SSC-L) and the IEEE Journal of Electromagnetics, RF and Microwaves in Medicine and Biology (J-ERM). He is the recipient or co-recipient of the 2016 Stanford University Tau Beta Pi Award for Excellence in Undergraduate Teaching, 2015 NSF CAREER award, 2014 DARPA Young Faculty Award (YFA) including the Director’s Fellowship in 2016, 2013 Hellman faculty scholarship, and best paper awards from several conferences including ISSCC (2010), VLSI Circuits (2014), RFIC symposium (2008 and 2011), ICUWB (2013), PIERS (2015), and the MTT-S BioWireless symposium (2016).

    Flexible bioelectronic medicines

    Abstract: Bioelectronic medicines are the next generation of neuromodulation devices: small active three-dimensional neural interfaces able to modulate nerve activity by targeting a specific neural region. They aim to treat a number of conditions, such as diabetes and asthma, in a tailored (per individual) and reversible fashion, avoiding the side effects of conventional drug-based interventions (pharmaceuticals). They achieve so by recording signals from the respective nerves, extracting information and using it as feedback to electrically stimulate the neural region in a closed-loop manner.

    Current technologies for active implants have not yet managed to achieve the miniaturisation and integration levels required for the development of bioelectronic medicines. For such breakthrough devices, novel concepts need to be explored, developed, and tested.

    In this talk I will present my current activities as well as my vision on realizing the first flexible three-dimensional graphene active implant, for safe chronic neural stimulation and recording from the peripheral nerves.

    Cryo-CMOS for Quantum Computing: does it work?

    Quantum computing holds the promise to change our lives by efficiently solving computing problems that are intractable today, such as simulation of quantum systems for synthesis of materials and drugs. A quantum computer comprises both a quantum processor and a classical electronic controller to operate and read out the quantum devices. The quantum processor must be cooled at cryogenic temperature in order to show quantum behavior, thus making it unfeasible to wire thousands of signals from the cryogenic quantum devices to a room-temperature controller.

    While this issue can be solved by placing also the electronic controller at cryogen¬ic temperature, which electronic technology is the best choice for its implementation? This talk will address the challenges of building such electronic controller, and answer whether a standard CMOS technology can be employed for the required analog and digital circuits operating at 4 K and below.

    Advanced Antenna Arrays for Modern Radar and Communication Systems

    Abstract: Several of today’s radar and wireless communication applications are shifting their operation to higher frequency to fulfil more demanding requirements on resolution, compactness and data rates. For this reason, there is a growing need to develop low-cost integrated circuit transceivers working at millimeter and sub-millimeter waves.

    However, on-chip antennas are currently characterized by very poor radiation efficiency and extremely narrow bandwidth. My approach of combining the concepts of connected arrays with artificial dielectrics will solve the inefficiency problem and enable high-efficiency on-chip antenna designs.

    Similar concepts can be also realized at microwave frequencies in printed circuit board, allowing for low-cost phased array antennas with state-of-the-art performance in terms of scan range, bandwidth and polarization purity.

  • Rob Remis
    Imaging with Waves

    We present an overview of our current wave field imaging and inversion research. Effective inversion strategies for important applications in Magnetic Resonance Imaging (MRI), nano-optics, and subsurface monitoring will be discussed. In particular, dielectric shimming (shaping of the radio frequency field in MRI) as well as inversion algorithms that determine the dielectric properties of various tissue types based on measured MRI data will be considered, and state-of-the-art model-order reduction techniques for large-scale wave propagation problems will be discussed as well.

On December 12 we organize the next Microelectronics Colloquium to introduce three new Assistant Professors (Tenure Trackers) of the Microelectronics department. They are happy to present a lecture about their research.

The colloquium start at 15.00 hrs. there will be a drink afterwards in the foyer.
Location: Theatre of Culture Builing (38) Mekelweg 10.
Please register online if you want to attend, latest December 5.

  • Masoud Babaie: Pushing The Limits of CMOS Circuits for Emerging Technologies
    Within the next few years, quantum processors, Fifth Generation (5G) cellular systems and the wireless Internet-of-Things (IoT) are expected to see significant deployment to realize more integration between the physical and digital worlds, promising enormous computation power, high data rate communications and enabling more objects to be remotely sensed and controlled.

    This talk will address some of the main challenges in the design and implementation of IoT devices, mm-wave 5G transceivers, and cryogenic CMOS controller for quantum computers. An overview of my past and ongoing research activities will be also presented, with emphasis on novel solutions to improve power efficiency and spectral purity of RF/mm-wave transceivers.

  • Morteza Alavi: Universal Transmitters for 5G
    Today, our daily activities are intertwined with the Internet. The ever-growing demand to swiftly get access to the data-cloud systems leads to huge data traffic. In order to seamlessly transmit and receive these gigantic data, _ 40 GB, agile radio-frequency (RF) transceivers are inevitable.

    These radios must be capable of supporting the current and future communication standards such as 5th generation of wireless mobile communications. The ultimate goal is that they can be implemented as universal radios whose modes of operation can be defined by their clients. To address these demands, RF transmitters are currently reinvented and are directed towards digital-intensive architecture. In this short presentation, we will briefly describe the strengths,possibilities, and challenges that exist for these advanced transmitters. First and foremost, the concept of RF-DAC based transmitters will be introduced. Next, the talk will review various RF-DAC based transmitters that have already been implemented at ELCA. Eventually, the presentation will concisely unveil the future directions of the research of these software-defined transmitters at ELCA.

  • Faruk Uysal: Distributed Radar Networks: Beyond a single radar
    The number of operational radar is rapidly increasing due to the growing demand of the remote sensing. Software defined radio and emerging single-chip radar technology make use of radars in every aspect of life such as autonomous driving, safety and security applications. With the increase of active transmitters, spectrum management and coexistence started to become a concern for some radar systems. In this talk, the previous applications of waveform, frequency agility will be reviewed to bring multi-functionality to the modern radar system. Finally, we will discuss the future research for distributed radar networks and how to fuse data from various radars to acquire different aspects of a target to be viewed simultaneously.

Wireless Power Transfer and Optogenetic Stimulation of Freely Moving Rodents

Farnaz Nassiri Nia

Animal studies are commonly used to test the feasibility and effectiveness of promising novel neuroscience research ideas. One such new technique is optogenetic stimulation, which refers to stimulation of the brain by means of light. Current optogenetic stimulation methods use tethered setups and, typically, the animal-under-study is put into a fixed position. This introduces stress, an obvious reduction in animal welfare, and may thus influence the experimental results. Hence, an untethered setup is highly desirable. Therefore, in this thesis, we propose a complete wireless optogenetic stimulation setup, which allows for full freedom of movement for multiple rodents-under-study in a 40x40x20 cm environment.

This thesis includes a thorough design space exploration and the subsequent development of: an inductive wireless link, a wireless receiver module that resides on the animal, and novel micro-LED array implants.

From Devices to Systems: New MEMS for radio frequency applications

Cristian Cassella
North-eastern University, Boston

We would like to invite you to our Laboratory of Electronic Components, Technology and Materials (ECTM) 2016 Autumn event with a special guest lecture. The lecture will be given by Dr. Cristian Cassella who is currently an associate research scientist in the Electrical and Computer Engineering department at North-eastern University, Boston. His talk will cover:

“The operation and performance of two new-classes of Aluminium Nitride (AlN) piezoelectric RF resonators. The first is a fully-passive MEM-based sensor for near-zero power detection in radios. Such sensor behaves as a trigger capable of activating the CMOS circuitry through extremely low-power (-60 dBm) wake-up signatures. The achievement of such a low-power RF-sensor is a key advance towards the commercialization of energy-efficient wireless platforms, with supreme battery-time. The second system is a MEMS-based RF circulator for multiband SPAR platforms, thus relying on the same carrier frequency for both transmitter and receiver modules.”

We will have the following program with plenty of room for questions:

In-vivo multicell inferior olivary recordings: alternative design methods for creating cheap and flexible electrode structures

Joost Kerpels

In order to allow neuroscientists to do in-vivo recordings on hard to reach brain tissue, such as the Inferior Olivary Complex, specially designed electrodes are required. Although a variety of electrodes are commercially available, they are usually expensive and it is hard to rapid prototype new designs.

This thesis describes the design process of three electrode array designs, each improved based on the findings of the previous one. The first design was made using a FlexPCB production technique, on which gold spots were added to create conducting measuring sites. The second design combined this technique with commercial microwire electrodes. The third design used 3d-print technology combined with microwire electrodes to create an electrode array.

All designs were tested in in vivo measurements on mice. Although successful measurements were done, the robustness and reproducibility needs to improve in order for this technique to really be applicable in a laboratory environment. Furthermore, the peripherals need to be improved in order to minimize the system to create a wearable system and perform recordings on wake animals.

Direct fabrication of micron-scale structures using Super Inkjet technology

Dr. Kazuhiro Murata, Mr. Kotaro Shimizu
SITechnology, Inc.

We have developed a super-fine inkjet technology (SIJ) that enables extremely fine pattern formation using droplets measuring less than 1 micrometer in diameter. By using conductive ink based on nano-metal particles, direct fabrication of circuits and three-dimensional structures having a feature size of just a few microns are achieved. Moreover the SIJ is capable of printing with a wide variety of inks, for example, insulators, organic semiconductors, light emitting polymers, bio-materials and UV curable polymers. The potential of the SIJ technology and its application to cutting-edge areas, such as flexible electronics, printed electronics, fine interconnect and others will be shown

Several Key Technologies for Emerging Applications and Recent MEMS/NEMs research progress in IMETU

ShaoJun Wei, Zewen Liu

ShaoJun Wei: Several Key Technologies for Emerging Applications
There are many emerging applications, such as cloud computing, big data, mobile internet, internet of things (IoT) , wearable device, smart hardware, and etc.. All of them need integrated circuits. With a huge population basis, China has an inborn advantages in this circumstance but with many challenges. Smart sensor, extremely low power pre-processing, micro assembly, high energy efficiency computing, low power high reliable memories are indispensable. We are entering a different ear while technologies we are familiar today should be pushed to their limits. In this presentation, the background of mobile internet, wearable devices, implanted hardware/software platform, IoT will be introduced and then several related technologies will be discussed with the emphasis on 3D Nand and reconfigurable computing. As these emerging applications are rapidly developing, it is very difficult to predict their evolution. Although semiconductors surely play a key role in these applications, with nanometer feature size and very high cost, how to find a way to support the low price and low margin applications is a big challenge.

Zewen Liu: Recent MEMS/NEMs research progress in IMETU
The MEMS and sensors research activities in IMETU ranges from process, materials to devices and packaging. A diversity of device had been recently developed such as sensors and MEMS energy harvester, super-capacitor for energy storage, microlens and RF MEMS. With the fast technology evolution, NEMS devices such as grapheme based device, nanohole and cantilevers are also explored which opens novel application in trace chemical sensing, flexible electronics and single DNA molecule detection. The highlights of the presentation are RF MEMS for modern communication and Nanopores for future DNA sequencing application. The prospect of integration of all devices on a chip for future IOT or smart city and the possible technical challenges will be also discussed.

Dimes Colloquium

Linear and nonlinear springs in electrostatic micro-actuators

David Elata
Technion - Israel Institute of Technology

In this presentation I will discuss the static and dynamic responses of mechanical springs that are used in electrostatic actuators. With respect to quasi-static applications, I will show how nonlinear mechanical springs can be used to counteract the nonlinear electrostatic attraction forces in gap-closing actuators. Instead of the pull-in instability, we may achieve an extended stable range with a linear voltage-displacement relation. Alternatively, beyond what would have been the pull-in point, we may achieve a constant voltage for any displacement. This effectively turns the transducer into a rechargeable mechanical battery, which is a neat design though mostly impractical. With respect to dynamic applications, I will show why the standard folded beam suspension, which is supposed to be linear by design, induces a nonlinear response in electrostatic comb-drive resonators. I will present a new suspension design which solves this problem.

MEST Colloquium

Electronics in Nano-Era: Are we Facing a Reliability Wall?

Said Hamdioui

The talk will address technology scaling and its impact on different aspects of IC and electronics, and in particular the emerging reliability bottlenecks. First the basics of scaling will be covered, together with its impact on integration density, performance and power. The technology outlook will be analyzed in order to extract the challenges with respect to design, test and reliability both for near and long terms. IC realization process will be (re) defined while considering the technology trends and business pressure. Possible ways for the realization of future systems will be discussed.

DIMES colloquium

Probabilistic Design for Reliability in Electronics and Photonics: Role, Attributes, Challenges

Prof.dr. Ephraim Suhir
Portland State University, USA

The recently suggested probabilistic design for reliability (PDfR) concept is based on:1) highly focused and highly cost-effective failure oriented accelerated testing (FOAT),aimed at understanding the physics of the anticipated failures and at quantifying, on the probabilistic basis, the outcome of FOATs conducted for the most vulnerable element(s) of the product of interest and the most likely and meaningful combination of possible stressors (the principle of superposition does not work in reliability engineering), and 2) simple and physically meaningful predictive modeling (PM), both analytical and computer-aided, aimed at bridging the gap between what one "sees" as a result of FOAT and what he/she will supposedly "get" in the field. FOAT and PM based sensitivity analysis (SA) algorithms are developed as by-products.

The PDfR concept is based on the recognition of the fact that nobody and nothing is perfect, and that the difference between a highly reliable and insufficiently reliable product is merely in the level of its probability of failure. If this probability (evaluated for the anticipated loading conditions and the given time in operation) is not acceptable, then such a SA can be effectively employed to determine what could be possibly changed, in terms of materials, geometries, application restrictions, etc., to improve the situation.

The PDfR analysis enables one also to check if the product is not "over-engineered", i.e., is not superfluously robust: if it is, it might be too costly: although the operational reliability cannot be low, it does not have to be higher than necessary either, but has to be adequate for the given product and application. This means that when both reliability and cost-effectiveness are imperative, ability to quantify reliability is a must. In this seminar the major PDfR concepts will be illustrated by case studies and practical examples. Although some advanced and subtle PDfR predictive modeling techniques have been recently developed for quantifying and assuring reliability of electronic and photonic products, especially those intended for aerospace applications, the practical examples addressed employ more or less elementary analytical models.
