Abstract:
Achieving energy-efficient “Green” communications requires the cooperation of all blocks within a communication system. This includes the digital and analog basebands, the transmitter, the receiver, the protocol, and most importantly the signal modulation selected. Optimizing any one of these, which is by far the most common approach, leaves the entire system far from its optimum efficiency. But when the entire system is jointly designed for optimum efficiency in the presence of all communication throughput requirements, significant energy savings relative to conventional design can be realized. These techniques hold equally for wireless and wireline communication channels.
This presentation begins with the fundamental physics of total energy efficiency, and discusses the resulting circuit operating aspects necessary to achieve the best available efficiency. Then the system aspects of modulation properties and protocol are derived that are necessary to allow access to the derived circuit optimal efficiencies. Collection of all these results into a set of joint optimization parameters is then presented as the fundamental requirements for achieving Green communications systems.

BRAINWAY: Cognitive Computer Architecture with Applications in Health Care and Personalized Medicine
Date: March 28th, 2016
co-sponsored by IEEE SCV SSCS, IEEE SCV CS
Speaker: Prof. Andreas Andreou, The Johns Hopkins University, IEEE Fellow, IEEE CAS Distinguished Lecturer
Abstract:
Since the invention of the integrated circuit -the chip in short- in the 1950’s, the microelectronics industry has seen a remarkable evolution from the centimeter scale devices created by Jack Kilby millimeter scale integrated circuits fabricated by Robert Noyce to today’s 8nm feature size MOS transistors. During this time, not only have exponential improvements been made in the scaling of size and the density of devices, but CAD and workstation technologies have advanced at a similar pace enabling the design of complete truly complex Systems On a Chip (SOC). The advances in the microelectronics industry have also enabled the proliferation of computational fields for bio-informatics, systems biology imaging and multi-scale multi-domain modeling. Semiconductor technology is contributing to the advancement of biotechnology, medicine and health care delivery in ways that it was never envisioned; from scientific grade CMOS imagers to silicon photomultiplier and ion sensing arrays. The stunning convergence of semiconductor technology and life science research is transforming the landscape of the pharmaceutical, biotechnology, and healthcare industries, signaling the arrival of personalized and molecular-level imaging diagnosis and treatment therefore speeding up the pace of scientific discovery, and changing the practice and delivery of patient care. Whether through
tissue and organ imaging, Labs-on-Chip or genome sequences, biotechnology and modern medical diagnostics are generating a staggering amount of data stored in data centers! However, computing in data centers, the engines behind our insatiable desire for global communication, instant connectedness and interaction comes at an economic and environmental cost. Future projected needs in data centers are data intensive applications in Cognitive Computing Technology (CCT). CCT aims at advancing intelligent software and hardware that can process, analyze, and distill knowledge from vast quantities of text, speech, images and biological data ultimately with and as much nuance and depth of understanding as a human would. To meet the scientific demand for future data-intensive CCT for every day mundane tasks such as searching via images to the uttermost serious health care disease diagnosis in personalized medicine [1], we urgently need a new cloud computing paradigm and energy efficient i.e. green technologies.
The BRAINWAY project in my lab is aimed at the design of an energy efficient Cognitive Processor Unit (CogPU) that combines Ultra-Low-Voltage (ULV) circuit techniques with brain inspired chip-multiprocessor network-on-chip (NoC) architecture, fabricated in 3D CMOS technology. The design of the CopPU architecture is based on the recently developed mathematical framework for architecture exploration and optimization [2], where neurons are abstracted as digital arithmetic logic units and communication processors [3]. We estimate, that such highly energy efficient CogPU inference engine will provide an energy efficiency gain of about ×65 by using ULV techniques and massive parallelism, a gain of about ×10 by relying on its SOC 3D DRAM, and a gain of about ×15 by relying on new memory based Bayesian inference computational structures. This yields an aggregate improvement factor in energy efficiency of about ×10000, roughly four to five orders of magnitude with respect to present day state-of-the-art. The first generation silicon for the BRAINWAY architecture was taped out in the Tezzaron 3D CMOS technology. The returned chips from 3D CMOS logic stack have been tested fully functional.

Challenges and Opportunities of circuits and systems on Internet of Things
Date: April 20th, 2016
co-sponsored by IEEE SCV CPMT, IEEE SCV CES
Speaker: Yen-Kuang Chen, Ph.D., IEEE Fellow, Principal Engineer at Intel Corporation
Abstract:
This seminar aims to discuss the technical trends and challenges of circuits and systems on Internet of Things. Rapid advancement of networking technologies together with extreme miniaturization of computing and communication devices enable a host of new and exciting applications and services that connect the physical and the computational worlds. In the future, digital sensing, communication, and processing capabilities will be ubiquitously embedded into everyday objects, turning them into the Internet of Things (IoT). In this new paradigm, smart devices will collect data, relay the information or context to each another, and process the information collaboratively using cloud computing and similar technologies. This paradigm shift creates numerous challenges and opportunities for engineering. For example, in the future, enormous numbers of sensors will be deployed. The costs of servicing such sensors will be a major concern. It is often almost impossible to replace sensor batteries once they are in the field. Therefore, one major challenge is low power sensor design, or designs which do not require a battery change over the lifetime of the sensor. For example, if a sensor is deployed on an animal for tracking purposes, the battery of the sensor should outlive the animal. This creates a demand for energy-efficient designs. This seminar will discuss the challenges and opportunities of circuits and systems on Internet of Things.

Location: This event is held at Maxim Integrated Headquarters not at the usual venue at TI
Abstract:
Miniaturized electronics, when placed inside the body, can wirelessly monitor and modulate internal activity and thus hold promise as a new class of treatments for disorders. The development of such bioelectronic medicines requires wireless interfaces that are tiny and operate deep in a complex electromagnetic environment. In this talk, I will describe a new method for electromagnetic energy transfer that exploits near-field interactions with biological tissue to wirelessly power tiny devices anywhere in the body, including the heart and the brain. I will discuss engineering and experimental challenges to realizing such interfaces, including a pacemaker that is smaller than a grain of rice and a fully internalized neuromodulation platform. These devices can act as bioelectronic medicines, capable of precisely modulating local activity, that may be more effective treatments than drugs, which act globally throughout the body.

- OVERVIEW:
- As data rates increase rapidly in high speed systems — such as in SerDes and memory systems — to meet the bandwidth growth required by various applications, the electrical performance of packages has become critical. In addition, the role of new emerging 2.5D and 3D IC packaging platforms with ever-increasing system integration requirements have made the role of packaging even more important. The sources of signal loss, noise coupling and discontinuities in packages must be fully understood and minimized when designing packages. At the same time, the design and development of packages have to meet cost, performance, form factor and reliability goals. In this talk we will examine the key electrical characteristics: signal loss, signal crosstalk, return loss, mode conversion, power integrity and other important factors affecting the bandwidth of high-speed systems. These key performance metrics are discussed using measurement results from various package designs.

Trends in Broadband Converters and the Quest for the Software Defined System
Date: September 22nd, 2016
IEEE SCV CAS proudly co-sponsors a special technical seminar on Thursday September 22, 2016 by David Roberson from Analog Devices. The title of the talk will be on:
“Trends in Broadband Converters and the Quest for the Software Defined System”
Abstract:
The concept of a “software defined radio”, “software defined instrument” or any “software defined” system is to move all the signal processing functions into the digital/software domain, thereby making the system highly reconfigurable. The principle is simple enough, but actually realizing workable systems is challenging, since the performance demands on the data converters can be daunting, not only in bandwidth, but in dynamic range. This talk will explore some of the progress that has been made over the last 15 years, with perspectives on both the driving applications and how converter technology has advanced in an effort to meet the applications challenges.
Bio:
David H. Robertson has been with the Data Converter group of Analog Devices since graduating from Dartmouth College in 1985. He has worked on a wide variety of high speed D/A and A/D converters on complementary bipolar, BiCMOS and CMOS processes. He has held positions as a Product Engineer, Design Engineer, and Product Line Director and VP of Analog Technology, working with product development teams in the US, Ireland, Korea, Japan, and China. Dave is presently the Product and Technology Director for ADI’s High Speed Converter group.
Dave holds 15 patents on converter and mixed signal circuits, has participated in two “best panel” International Solid State Circuits Conference evening panel sessions, and was co-author of the paper that received the IEEE Journal of Solid State Circuits 1997 Best Paper Award. He served on the ISSCC technical program committee from 2000 through 2008, chairing the Analog and Data Converter subcommittees from 2002 to 2008.

Demystifying Linear Time Varying Circuits
Date: October 20th, 2016
IEEE SCV CAS proudly co-sponsors an IEEE SCV SSC distinguished lecturer seminar on Thursday October 20th, 2016 by Shanthi Pavan, IIT-Madras, with the title:
“Demystifying Linear Time Varying Circuits”
Abstract:
An analog/mixed-signal designer encounters time varying circuits everywhere – sample-and-holds, chopper stabilised amplifiers, mixers, switched-capacitor amplifiers and filters, discrete and continuous-time delta sigma modulators, N-path filters. The analysis of signals and noise in these circuits is often associated with messy mathematics and algebra.
This talk aims to demystify linear (periodically) time varying circuits. Starting from first principles, intuition behind various aspects of time-varying circuits and systems will be given. This intuition is illustrated with case studies of practical circuits and systems, like chopper-stabilised amplifiers and continuous-time delta-sigma modulators.
Bio:
Shanthi Pavan obtained the B.Tech degree in Electronics and Communication Engg from the Indian Institute of Technology, Madras in 1995 and the Masters and Doctoral degrees from Columbia University, New York in 1997 and 1999 respectively.

Challenges and Design Considerations for High-Efficiency Modern Wireless RFIC Transmitters
Date: November 17th, 2016
IEEE SCV CAS proudly co-sponsors an IEEE SCV SSC distinguished lecturer seminar on Thursday November 17, 2016 by Osama Shanaa, Mediatek Inc with the title:
“Challenges and Design Considerations for High-Efficiency Modern Wireless RFIC Transmitters”
Abstract:
Modern communication systems are rapidly increasing in complexity fueled by high customer demand for data-rich media streaming over the airwaves. With limited, and sometimes fragmented, available spectrum, very complex modulation schemes with relatively high signal bandwidth are used to be able to “pack” such high data contents for wireless streaming. As a result, tremendous pressure is now put on RFIC designers to deliver circuits that can handle such complex modulation and maintain the required high signal integrity while still be power efficient. This talk walks the audience through design challenges and considerations for high-efficiency transmitters and what areas of research are needed to enable and enhance such circuits moving forward. A dual band CMOS digital transmitter supporting WiFi 802.11 a/b/g/n is used as a design example of a potential technique to address some of the highlighted issues.
