“Reconfigure the World: Adaptive-Transfer-Function and Multi-Band RF Filtering Devices for Emerging Wireless Systems”

Next-generation multi-purpose wireless-communications (e.g., 5G) and multi-mode remote-sensing systems demand highly-versatile RF front-ends capable of supporting them. As a result, a lot of interest has recently been detected in the development of advanced high-frequency electronics featuring increased levels of spectral adaptivity and multi-band operation. In particular, a considerable attention is being dedicated to the design of fully-reconfigurable single/multi-band RF bandpass filtering devices as key blocks to perform the adaptive-signal-band-selection process required by these systems. On the other hand, the ever-growing saturation of the radio-spectrum resource has led to critical electromagnetic-coexistence scenarios between the plurality of co-located RF systems that exploit it. In this case, the availability of fully-controllable multi-notch RF filters to suppress spectrally- and power-agile interferers is very desirable. The purpose of this seminar is to present an overview of recent contributions in the research field of RF filtering devices with highly-reconfigurable and multi-band transfer function. This includes both multi-passband and multi-band stop components for multi-channel-selection and multi-interference-mitigation applications, respectively. Furthermore, their operational and design foundations, as well as a rich variety of experiment demonstrators in different bands and high-frequency technologies (e.g., planar, 3-D, lumped-element, acoustic-wave, and integrated ones), will be shown.

“From Transistors to Swarm Systems: The Evolution of Design Methods and Tools in the last 40 Years”

Giovan Battista Vico, a philosopher and historian who lived across the XVII and XVIII centuries, was the first to note in his masterpiece “Scienza Nuova” (New Science) that the history of man and his endeavors follow a cyclical pattern. Economies, as well as the power of nations, have exhibited a clear and cyclical behavior. Electronic Design Automation (EDA) has not escaped this fundamental law. EDA started in the late 1960s when large companies such as IBM and Bell Laboratories were developing new products based on Integrated Circuit technology. The ICs of the time had only a few tens of transistors but the design costs were raising and the need to obtain circuit right the first time became clear. The scientific content of tools and methods for ICs ranged from physics to mathematics in a mix that is rare to see in any other engineering field.

EDA technology advances have oscillated between verification and synthesis, the perception in the mind of the electronic design community of EDA has been rising and falling in a regular pattern, EDA companies have risen and declined, the consideration of the financial community for EDA has been periodically increasing and decreasing, and the algorithms used in EDA have swung from general purpose techniques borrowed from mathematics, computer science, operation research, and artificial intelligence, to ad hoc techniques that leverage the nature of the specific design problem to be solved. Prof. Sangiovanni-Vincentelli will show that progress is achieved when new methodologies crystallize, with new tools and techniques acting as catalysts, that the construction of layers of abstraction are the steps that have helped us reach new heights.

His take in this talk is that the great success of Electronic Design Automation to enable the design of chips with more than 1 Billion transistors over a span of 40 years can be replicated in other sectors including traditional industries such as construction, and novel sectors such as synthetic biology, if its essential elements are distilled appropriately. He will show how they are approaching these extensions and what challenges they are facing.

Throughout the talk, Prof. Sangiovanni-Vincentelli will intersperse considerations about his scientific and industrial journey from a theory-oriented professor to an “entrepreneur”.

Alberto Sangiovanni-Vincentelli is the Edgar L. and Harold H. Buttner Chair of EECS, University of California, Berkeley, where he is Special advisor to the Dean of Engineering for Entrepreneurship and Chair of the Faculty Advisors to the Berkeley Accelerator, SkyDeck. Awards (among others): Kaufman for pioneering contributions to EDA; IEEE/RSE Maxwell Medal “for groundbreaking contributions that have had an exceptional impact on the development of electronics and electrical engineering or related fields” and the EDAA Lifetime Achievement Award. He co-founded Cadence and Synopsys, the two leading EDA companies and is Member of the Board of Directors of Cadence, KPIT, ISEO, ExpertSystem, QuantumMotions (Chairman), Phoelex (Chairman), Cy4Gate, Exein and Cogisen. He consulted for several companies including Intel, IBM, ST, Mercedes, BMW, UTC, Lendlease and GM. He is the Chairman of the International Advisory Council, Milano Innovation District. He is member of the US National Academy of Engineering. He is an IEEE and ACM Fellow. He was awarded an Honorary Doctorate from Aalborg University, from KTH (Sweden) and from IAG (Krakow, Poland).

“Flexible Interference Robust CMOS Radio Receivers”

The radio spectrum is becoming more and more crowded, and radio receivers are typically interference limited. As there is a demand for multi-mode flexible radio devices, traditional dedicated narrowband filtering no longer satisfies. During the last decade, several new radio receiver architectures and circuits have been proposed which offer more flexibility than traditional receivers with dedicated fixed filtering, while still achieving good sensitivity and robustness for interference. Different names have been used to refer to these receivers, e.g. reconfigurable receiver, multi-band receiver, wideband receiver, SAW-less receiver, software defined radio receiver or cognitive radio receiver. These receivers have in common that they all aim for a high dynamic range while relying less on fixed filters. This talk reviews several proposed concepts, e.g. linearization techniques, noise and distortion cancelling, Low Noise Transconductance Amplifiers followed by current-mode mixing, mixer-first receivers, frequency-translated N-path filtering, harmonic rejection and spatial interference rejection.

Eric Klumperink received his PhD from Twente University in Enschede, The Netherlands, in 1997 where he is currently an Associate Professor. He teaches Analog and RF CMOS IC Design and guides research projects focussing on Software Defined Radio and Beamforming.

“State-of-the-Art Automotive Radar System Architectures and What Else We Can Do with Them” webinar by Prof. Gardill

Automotive Radar operating in the 77 GHz and 79 GHz bands is the largest market for mmWave systems. Consequently, a de-facto standard system architecture has evolved which is used by most devices on the market and under current development. Modern automotive radars are to a large extent software defined and enable adaptive selection of waveform parameters as well as dynamic utilization of RF subsystems such as transmit and receive channels. This flexibility is the key-enabler for implementing multi-purpose radar sensors, which can realize functions from adaptive cruise control down to automated parking all in one device. Together with the high-volume of automotive radars also comes a rapid cost-reduction. Consequently, they become more and more attractive for solving various other sensing challenges: something else they have originally been designed for.

After reviewing the state-of-the art system architecture of automotive radar sensors, this presentation will introduce some novel ideas and applications how performance of that automotive “mass-product” can be further improved and how their flexibility allows for a widespread use, far beyond the traditional adaptive cruise control.

Between 2015 and 2020 he was R&D engineer and research cluster owner for optical and imaging metrology systems at Robert Bosch GmbH. Later he joined InnoSenT GmbH as head of the group radar signal processing & tracking, developing together with his team new generations of automotive radar sensors for advanced driver assistance systems and autonomous driving.

“Mixed-Signal Computing for Deep Neural Network Inference” – webinar by Prof. Boris Murmann from Stanford University, USA

Modern deep neural networks (DNNs) require billions of multiply-accumulate operations per inference. Given that these computations require relatively low precision, it is feasible to consider analog arithmetic, which can be more efficient than digital in the low-SNR regime. However, the scale of DNNs favors circuits that leverage dense digital memory, leading to mixed-signal processing schemes for scalable solutions. This presentation will investigate the potential of mixed-signal approaches in the context of modern DNN processor architectures, which are typically limited by data movement and memory access. We will show that dense mixed-signal fabrics offer new degrees of freedom that can help alleviate these bottlenecks. In addition, we will derive asymptotic efficiency limits and highlight the challenges associated with data conversion interfaces (D/A and A/D) as well as programmability. Finally, these findings are extended to in-memory computing approaches (SRAM and RRAM-based) that are bound by similar constraints.

Boris Murmann is a Professor of Electrical Engineering at Stanford University. He joined Stanford in 2004 after completing his Ph.D. degree in electrical engineering at the University of California, Berkeley in 2003. From 1994 to 1997, he was with Neutron Microelectronics, Germany, where he developed low-power and smart-power ASICs in automotive CMOS technology.

“Millimeter-Wave Transceivers for High Volume Applications” – webinar by Prof. Thomas Zwick, Karlsruhe Institute of Technology (KIT), Germany

The enormous technological progress accomplished over the last decades facilitates the utilization of millimeter-wave (mm-Wave) frequencies for mass products like automotive radars, industrial sensors, high-speed data communication links or medical applications. The main enablers are the semiconductor technologies with constantly improving cut-off frequencies reaching several hundred GHz. The dominant limiting factor though for the mass production of low-cost mm-Wave systems above 100 GHz is that, suitable packaging technologies are not yet finally available. The major issue for the packaging is to find a proper way to get all signals in and out of the package, since at mm-Wave frequencies interconnects are very difficult to realize and very lossy. One way out of the dilemma is to integrate the complete transceiver together with the antenna into one single package. Compactness is the key to low losses in mm-Wave interconnects. This also means that the antenna must be integrated into the package.
In this talk, a short overview on the packaging and antenna integration concepts for mm-Wave transceivers is provided together with several particular approaches.

Thomas Zwick (S’95–M’00–SM’06–F’18) received the Dipl.-Ing. (M.S.E.E.) and the Dr.-Ing. (Ph.D.E.E.) degrees from the Universität Karlsruhe (TH), Germany, in 1994 and 1999, respectively.

“Energy-Efficient Communication Technologies for Emerging Internet-of Things Applications”

Webinar

The ACRC (Advanced Circuit Research Center) in cooperation with the IEEE Solid State Circuits Society continues the series of “ACRC Semiconductor Webinars”  – insightful and enriching workshops held by international leaders and professionals of the semiconductors sector.

This time we are inviting you to a free online seminar on “Energy-Efficient Communication Technologies for Emerging Internet-of Things Applications” given by Prof. Patrick Mercier from University of California, San Diego.

Emerging Internet-of-Things (IoT) devices all require robust yet low-power wireless communications. Unfortunately, most current wireless standards do not intrinsically support low-power operation due to strict requirements on modulation formats, data rates, linearity, packet overheads, and so on. These restrictions impose minimum power consumption requirements for cellular standards (e.g., GSM, LTE, and 5G) and WiFi, but also surprisingly limit the ability of supposedly low-power standards (e.g., Bluetooth Low Energy and Narrowband-IoT) from reaching new application-enabling power levels. This presentation will outline the major challenges facing power reduction in modern wireless systems, and will describe several possible solutions to these challenges. Specifically, we will explore the use of wake-up receivers as a means to reduce the power overhead of between-node synchronization, including a look at a recent design operating at 9GHz. Then, we will discuss a variety of alternative communication schemes that can help to reduce the power of communication in WiFi and body-area-network systems by >1,000x through use of WiFi-compliant backscatter communication and magnetic human body communication systems, respectively. We will then introduce new circuit design techniques based on a topologically-derived “digitally-replaced analog” paradigm towards the implementation of efficient Li-ion-battery-connected RF power amplifiers for high-performance wireless systems.
