    Superconducting Single Flux Quantum Electronics: Solving Energy Problem in High-End Computing

    Abstract:
    The explosive growth of the Internet transformed data centers into large industrial scale computer facilities with extraordinarily high energy demands. From Google and Facebook to banking, cloud computing and supercomputing, an average data center already use as much electricity as a medium-size town. Besides just high energy costs, there is a compelling technical reason to improve energy efficiency of computing technologies. The development of the next generations of high-end computers will not be possible unless a significant improvement in energy efficiency is achieved over the technology available today. The heart of the problem is in a relatively low energy-efficiency of current computer circuit technologies consuming too much energy for computing, storing and moving data between processors and memories. Superconducting Single Flux Quantum (SFQ) technology is viewed as a possible Beyond-Silicon technology at a relatively matured stage of the development. I will review several key innovations happened just within last few years which dramatically increased a potential of superconductivity addressing known critical problems which prevented the use of superconductivity in high-end computing in the past. Superconducting SFQ digital circuits by virtue of their inherent low power dissipation, high speed, lossless interconnect present an excellent opportunity to dramatically increase energy efficiency of high-end computing. The long-standing memory problem is being addressed by a new class of cryogenic spintronics devices capable of co-integration with SFQ circuits and new superconducting spintronics elements, in which competing superconducting and magnetic order parameters co-exist to deliver new opportunities for electronics.

    Microelectronics for Radiation Detectors

    Abstract:
    Radiation detectors find application in several areas, the most prominent being medical imaging, national security, safeguard, and physics research. In order to achieve a high resolution, these detectors require specialized low-noise electronics, also known as front-end electronics. This seminar presents the most relevant technical and non-technical aspects of front-end electronics design for radiation detectors. The concepts of low-noise charge amplification, pulse shaping and equivalent noise charge are introduced.
    Front-end application-specific integrated circuits are regarded as a critical enabling technology without which both present and future radiation detector developments would be impossible. The deep knowledge of this specialized front-end design has traditionally belonged to a very limited number of research groups and institutions worldwide. A major challenge comes from the dramatic increase in demand, combined with the need for higher resolving capability, functionality and portability. These stringent requirements push the state-of-the-art to the limit and calls for continuous innovation. The rapid evolution of front-end ASICs is discussed and state-of-the-art developments are shown.

    Biography:
    Gianluigi De Geronimo received his Ph.D. in microelectronics from Milan Polytechnic in 1997. Shortly after that he joined the Instrumentation Division of Brookhaven National Laboratory, NY, where he specialized in the design of front-end integrated circuits for radiation detectors. He successfully developed several state-of-the-art ASICs implementing innovative circuits and frequently achieving record performance. He collaborates with several institutions and industries and is co-author of over 130 scientific publications and two book chapters.
    Dr. De Geronimo is a Visiting Research Scientist with the Nuclear Engineering and Radiological Sciences Department at the University of Michigan and an Adjunct Professor with the Electrical and Computer Engineering Department at the Stony Brook University where he teaches a course on microelectronics for sensors, and mentors of several MS and Ph.D. students. Recipient of the 2008 BNL Science and Technology Award, 2012 CSIRO Award, 2012 Battelle Inventor of the Year Award, and 2009, 2011, and 2014 R&D 100 Awards, he holds 20 patents and records of invention. He is editor of IEEE Transactions on Nuclear Science and reviewer for various journals and government institutions.

    Time Varying Circuits for Radio Receiver Applications

    Abstract:
    Recently, various ultra-low power applications such as wearable devices, biomedical devices and Internet-of-Things (IoT) have been developed opening up a new domain of integrated circuits design. In these applications, ultra-low power circuit techniques for improving the energy efficiency have been the main research focus. One of the most challenging blocks in ultra-low power systems is SRAM. A number of state-of-the-art circuit techniques have been proposed to tackle the ultra-low power SRAM design issues. In this talk, I will briefly explain various design issues in SRAM followed by various state-of-the-art design techniques. Some recent research works from my research group in NTU will also be introduced.

    Biography:
    Sharp, programmable, linear, integrated filters are enabling components for software defined and cognitive radio applications. However, they are difficult to realize: SAW and MEMS based filters are sharp and linear but not very programmable; active filters can be sharp and programmable but are not very linear; sampled charge domain filtering is sharp and programmable but the burden of the linearity is on the front end voltage-current converter. This talk descirbes an alternative approach that uses time-varying (as opposed to time-invariant) circuits to realize sharp, programmable, linear, integrated filters. The technique exploits sampling aliases to effectively realize very sharp, linear filtering prior to sampling. This talk will describe the basics of this time-varying circuit design approach and illustrates its application to radio front-ends and spectrum scanners. Measurement results from recent prototype integrated circuits will also be presented.

    From Low power to Predictive Analytics for VLSI - Beyond Guessing

    Abstract:
    Moore’s law drives lowering cost/function ratio and thus pushes addition of more functions on a chip. This requires reduction in power. In Internet of Everything (IoE), System on Chip (SOC), flexible electronics, 3D printing the drive towards low power while maintaining functionality will be essential. Also power has become the key driving force in high performance processor designs as the frequency scale-up is reaching saturation. In order to achieve low power system, circuit and technology co-design is essential. This talk focuses on pros and cons analysis of technology and circuit techniques from power perspective and various techniques to exploit lower power. The talk highlights fundamentals and the direction for low power optimization such as reduction in active, leakage, short circuit power and collision power will continue to be the focal area for in the scaled world. Conventional and advanced techniques (e.g. clock gating, power gating, longer channel, multi-Vt design, stacking, header-footer device techniques and new developments etc.) will be described for logic and memories. Finally key challenges in achieving low power will be described.
    As the technology pushes towards sub-14nm era, process variability and geometric variation in devices can cause variation in power, performance and functionality. Predictive Analytics to capture systematic and random variation and to aid in robust design optimization in nm regime will be discussed. Also the talk will describe future growth directions and role of such predictive algorithms.
