“Embedded Systems Design in the Era of AI” by Prof. Michael Huebner

The increasing demands of complexity, flexibility and self-organization of networked embedded systems require new solutions for the local processor architectures and firmware. This includes the ability to adapt to the requirements of an algorithm e.g. in relation to a sensor value measured by an Cyberphysical System. Artificial intelligence becomes ubiquitous and therefore enters also the domain of embedded systems and enables enormous opportunities in edge computing. This will introduce new degrees of freedom in embedded and Cyberpyhsical systems and is very promising to support the aforementioned demands tremendously. In this talk, possible solutions for next generation embedded systems with AI components will be introduced.

Michael Huebner is a Full Professor and leads the Chair for Computer Engineering at the Brandenburg University of Technology (BTU) in Cottbus, Germany, since 2018.

He is also Vice-President for research and transfer at BTU since December 2020.

He received his diploma degree in electrical engineering and information technology in 2003, his Ph.D. degree in 2007 from the University of Karlsruhe (TH), and did his habilitation in 2011 at the Karlsruhe Institute of Technology (KIT) in the domain of reconfigurable computing systems.

His research interests are in reconfigurable computing and particularly new technologies for adaptive FPGA run-time reconfiguration and on-chip network structures with application in automotive systems, incl. the integration into high-level design and programming environments.

“An Organic-Photoconductive-Film CMOS Image Sensor’s Advanced Technologies” by Kazuko Nashimura

We have developed a CMOS image sensor with an organic photoconductive film (OPF) laminated on pixel circuits, different from those of a conventional silicon image sensors, in which the organic thin film for photoelectric conversion and the charge storage part for signal charge accumulation are completely independent. In this presentation, we focus on the advantageous features of the OPF image sensor; [1] technology that realizes over 120 dB simultaneous-capture wide dynamic range; [2] global shutter technology achieving high saturation signals per unit square that is 10 dB higher than that of silicon image sensors with the global shutter function, without sacrificing pixel area; [3] RGB-NIR sensor technology capable of controlling NIR sensitivity by simply controlling the voltage applied to the OPF. Moreover, we introduce about 8K4K high resolution sensor technologies with 60fps high frame rate, 450ke- high saturation signals, and the global shutter function at the same time. We believe these features of the OPF image sensor will contribute to leaps in the imaging and sensing fields.

Kazuko Nishimura received the B.E. degree in mechanical engineering from Osaka University, and joined Panasonic Corporation where she engaged in high-speed analog-to-digital converters (ADCs) in 1995. She developed optical communication systems for fiber-to-the-home (FTTH), RF tuners and CMOS image sensors.

Course Abstract and Outline

The increasing demand for over-the-air data traffic imposes requirements for wireless protocols and transceivers to support wider (e.g., 160 MHz) channel bandwidths, higher order modulation schemes (e.g., 1k-QAM OFDM), and MIMO and multilink schemes to allow for the increased wireless throughput. As many wireless enabled devices are battery powered and mobile, there is also a continuous demand to improve power consumption, cost, and form factor. Reducing the power dissipation becomes even more critical with the simultaneous operation of multiple chains.

These trends have driven higher levels of integration of the radio, with digital SoCs, on advanced CMOS processes. However, implementing the transceiver on a deeply scaled process node presents major challenges from having to operate off low supply voltages. In addition, traditional RF designs require accurate transistor and passive models, which can become a time-to-market limitation for the whole SoC.

As a result, in recent years, there has been a shift in wireless transceivers toward digital radio architectures due to their more compact die area, scalability in advanced CMOS processes, and the improved power efficiency. Furthermore, digital circuit topologies open paths to include digital processing algorithms that can enhance the circuit capabilities beyond the traditional analog designs allow. Examples for such topologies include digital phase lock loops and digital transmitters that will be explored.

The course discusses the operation principles and the design of modern digital radio frequency circuit topologies and system architectures with enhanced digital signal processing. Two main examples will be presented and discussed in detail, the first of digital phase lock loops and the second of digital transmitters. Their basic operation principles and modeling will be discussed and compared to the equivalent analog radio components.

“Hardware Security and Safety of IC Chips” webinar by Prof. Makoto Nagata

IC chips are key enablers to a smartly networked society and need to be more compliant to security and safety. For example, semiconductor solutions for autonomous vehicles must meet stringent regulations and requirements. While designers develop circuits and systems to meet the performance and functionality of such products, countermeasures are proactively implemented in silicon to protect against harmful disturbances and even intentional adversarial attacks.

This talk will start with Electromagnetic Compatibility (EMC) techniques applied to IC chips for safety to motivate EMC-aware design, analysis, and implementation. It will discuss IC design challenges to achieve higher levels of hardware security (HWS). Crypto-based secure IC chips are investigated to avoid the risks of side-channel leakages and side-channel attacks, corroborated with silicon demonstrating analog techniques to protect digital functionality. The EMC and HWS disciplines derived from electromagnetic principles are key to establishing IC design principles for security and safety.

“Asynchronous Stream Computing for Low Power IoT – Asynchronous Stochastic Computing (ASC), Asynchronous Stream Processing (ASP) and Asynchronous Impulse Radio (AIR) for ubiquitous sensing at the Edge” webinar by Prof. Mircea R. Stan

Asynchronous circuits have many potential advantages over their synchronous counterparts in terms of robustness to parameter variations, wide supply voltage ranges, and potentially low power by not needing a clock, yet their promise has not been translated yet into commercial success due to several issues related to design methodologies and the need for handshake signals. Stochastic computing is another processing paradigm that has shown promises of low power and extremely compact circuits but has yet to become a commercial success mainly because of the need for a fast clock to generate the random streams.
In this talk we will go over three complementary circuit techniques: Asynchronous Stochastic Computing (ASC), Asynchronous Stream Processing (ASP) and Asynchronous Impulse Radio (AIR). These techniques combine the best features of asynchronous circuits with the best features of stochastic computing to enable extremely compact and low power IoT sensing nodes. Together they can fulfill the promise of smart dust, a concept that was ahead of its time and yet to achieve commercial success.

Mircea R. Stan is the Virginia Microelectronics Consortium (VMEC) professor at the University of Virginia.

“Closed-Loop Neuromodulation”

Facing a growing number of patients with neurological disorders, there are only limited therapeutic pharmacological measures which provide only temporary and mild amelioration of the devastating symptoms of these disorders. The use of electrical stimulation of the brain is a treatment option for patients with severe treatment-resistant disorders. Current deep-brain stimulation (DBS) approaches are hindered by inadequate technology that is low-precision and bulky, power-inefficient, and of limited diagnostic utility. The seminar will discuss a high-precision implantable neurotechnology for closed-loop neuromodulation of functional networks of the human brain. Key features of the technology are: 1) sensing from a high number of channels, 2) sensing concurrent with stimulation for true closed-loop operation, and 3) real-time secure wireless data telemetry. The proposed neurotechnology could revolutionize brain therapies in efficacy, size and cost of medical implants.

“Circuits and architectures with ultra-wide power-performance adaptation – going way beyond voltage scaling”

Wide power-performance adaptation down to nWs has become crucial in always-on nearly real-time and energy-autonomous SoCs that are subject to wide variability in the power availability and the performance target. Wide adaptation is indeed a prerequisite to assure continuous operation in spite of the widely fluctuating energy/power source (e.g., energy harvester), and to grant swift response upon the occurrence of events of interest (e.g., on-chip data analytics), while maintaining extremely low consumption in the common case. These requirements have led to the strong demand of SoCs having an extremely wide performance-power scalability and adaptation, so that they can relentlessly operate without interruption in spite of the highly-uncertain power availability.

In this talk, new directions to drastically extend the performance-power scalability of digital, analog and power management circuits and architectures are presented. Silicon demonstrations of better-than-voltage-scaling adaptation to the workload are illustrated for both the data path (i.e., microarchitecture) and the clock path in the digital sub-system. New directions to achieve full-system coordinated power-performance scaling are also discussed. Silicon demonstrations and trends in the state of the art of battery-light, battery-less and battery-indifferent SoCs are illustrated to quantify the benefits offered by wide power-performance adaptation, identifying opportunities and challenges for the decade ahead. Finally, an always-on mm-scale integrated system that operates uninterruptedly when solely powered by moonlight is demonstrated, paving the way to a new generation of always-on systems with little to no battery.

Massimo Alioto is a Professor at the ECE Department of the National University of Singapore, where he leads the Green IC group, and is the Director of the Integrated Circuits and Embedded Systems area and the FD-FAbrICS research center on intelligent&connected systems.

Course Abstract and Outline

Recent advances of silicon-based semiconductor processes and packaging technologies have accelerated the implementation of radar sensors for numerous mass-volume applications at mm-wave frequencies. CMOS and SiGe technologies seem to provide a very attractive solution for realization of mm-wave radar transceivers.

This first part of the lecture will start with the basic introduction of continuous-wave (CW) and pulsed radar systems. We discuss briefly the frequency regulations for automotive and consumer radar applications. Then we focus only on CW and FMCW systems and consider range, velocity and angular resolution. We discuss how to derive a specification of the radar system based on the specific radar application scenario, as e.g. link budget calculation, frequency chirp, dimensioning of filters and VGA in the analog baseband, choosing sampling rate and resolution of the ADC. Next, we discuss the impact of phase noise on radar systems, as e.g. range correlation effect. Further, we discuss the radar signal processing, range-Doppler map and detection of multiple targets. Finally, we discuss advanced topics as noise floor degradation by non-ideal mixing and TX to RX spillover cancellation and show integrated radar system examples. Then, we derive specification of the circuit blocks based on the system requirements and adress the design of the blocks separately in the second part.

The second part deals with the circuit design and physical implementation of the systems on chip (SoC) and systems in Package (SiP) for mm-wave radar applications. First, we repeat the basics of mm-wave design, as e.g. CMOS and bipolar transistor performance at mm-wave, passives at mm-wave, nonlinearity, noise, stability. Next, we discuss the design of mm-wave LNA, mixers (active and passive), VCO, Power Amplifier, frequency divider and multiplier. We discuss considerations on LO synthesis and distribution for large chips. Additionally, we discuss realization challenages of antenna on-chip and in package at mm-wave frequencies. Finally, we discuss examples of latest reported radar transceivers.

This course aims to provide a deep overview over modern radar systems for automotive and consumer applications. The students will get a broad scope starting from the radar sensing scenario, translating it into the block specification, designing the circuit blocks and realization of the transceivers. Novice designers can get an introduction to circuits and systems, while experienced mm-wave designers can expand their knowledge by connecting the circuits and systems for radar applications.

“A Flexible vision for RF ICs” by Dr. Matan Gal-Katziri

Flexible high-speed systems and architectures have promising and exciting applications at the intersection of communications, imaging, medicine and deployable arrays. The flexibility is expressed in terms of electrical reconfigurability, flexible circuit board materials, and lightweight, bendy interconnects between remote array elements. In this talk I will present my work at Caltech’s High-speed and holistic IC laboratory in developing such systems. Two key elements in our flexible schemes are the utilization of highly functional RFICs to minimize rigid component count, and a holistic, modular design approach which is crucial to future size scaling. Through the talk I will present several exemplary architectures for space, power transfer, communication and sensing applications, and will discuss the high-level considerations, implementation, challenges, and potential uses of such systems.

“Human-Centric Computing” by Prof. Jan Rabaey

The world as we know it is going through some major upheavals: climate change, pandemics and technology-induced societal changes are upsetting our world-picture with no real end in sight. Hence, an extremely relevant question is how ‘we humans’ are going to cope with this rapid evolution. One plausible answer is for us to use those same technologies to evolve ourselves, and to equip us with the necessary tools to interact with, survive, and prosper in spite of (or in light of) these changes.

Various wearable devices have been or are being developed to do just that. However, their potential to create a whole new set of human experiences is still largely unexplored. To be effective, functionality cannot be centralized and needs to be distributed to capture the right information at the right place. This requires a human intranet, a platform that allows multiple distributed input/output and information processing functions to coalesce and form a single application. In this presentation, we focus on the computational aspects of such an intranet, tasks that are complicated by the extreme energy and form-factor limitations imposed on the wearable (or implanted) devices. An important aspect is that the human intranet should not only be able to learn from experience, but capable of dealing with changes in both the environment and in itself. Moreover, it should be able to do so on a continuous base. Computational models, architectures and circuits that enable such capabilities at ultra-low energy and small form factor are hence needed. A glimpse of what may be possible will be presented.

Jan Rabaey is a Professor in the Graduate School in the EECS Department at the University of California at Berkeley, where he held of the Donald O. Pederson Distinguished Professorship for over 30 years before retiring. Before joining the faculty at UC Berkeley, he was a research manager at IMEC from 1985 until 1987. He is a founding director of the Berkeley Wireless Research Center (BWRC) and the Berkeley Ubiquitous SwarmLab, and has served as the Electrical Engineering Division Chair at Berkeley twice. In 2019, he also became the CTO of the System-Technology Co-Optimization (STCO) Division of IMEC, Belgium.

Prof. Rabaey has made high-impact contributions to a number of fields, including advanced wireless systems, low power integrated circuits, mobile devices, sensor networks, and ubiquitous computing. His current focus is of the interaction between the cyber and the biological world (amongst many other things.

He is the recipient of major awards, amongst which the IEEE Mac Van Valkenburg Award, the European Design Automation Association (EDAA) Lifetime Achievement award, the Semiconductor Industry Association (SIA) University Researcher Award, and the SRC Aristotle Award. He is an IEEE Fellow, a member of the Royal Flemish Academy of Sciences and Arts of Belgium, and has received a number of honorary doctorates. He has been involved in a broad variety of start-up ventures.
