Digitally Assisted Analog Circuit Design for Communication SoCs

DISTINGUISHED LECTURER SERIES"Digitally Assisted Analog Circuit Design for Communication SoCs"Prof. TERESA MENGStanford UniversityAbstract:The availability of high-speed network infrastructure and low-cost CMOS technology has dramatically changed the landscape of broadband communication in the past few years. To accommodate the ever increasing data rates, communication SoC design is no longer merely a circuit integration problem. The implementation of high-throughput communication SoCs with a power constraint requires a new design strategy for the embedded analog components. One solution is to exploit the computational capability of digital circuitry to continuously calibrate the mixed-signal and analog circuits and compensate for their ever more tenuous realization as technology is scaled and supply voltages are reduced. To support the computational requirements, digital processing architectures will be developed and implemented which have the efficiency of dedicated circuitry while allowing the flexibility to adapt to changing environments, algorithms, waveforms and circuit performance. In this talk, adaptive optimization techniques in combination with on-chip calibration will be applied to reducing the power consumption of an OFDM transmitter and a high-speed ADC. State-of-the-art developments in digitally assisted communication SoCs will be discussed, along with the opportunities for future innovations.Bio:Teresa H. Meng is the Reid Weaver Dennis Professor of Electrical Engineering at Stanford University. Her research activities during the first 10 years at Stanford included low-power circuit and system design, video signal processing, and wireless communications. She has received many awards and honors for her research work at Stanford: an NSF Presidential Young Investigator Award, an ONR Young Investigator Award, an IBM Faculty Development Award, a Best Paper Award and a Distinguished Lecturer Award from the IEEE Signal Processing Society, the Eli Jury Award from U.C. Berkeley, and awards from AT&T, Okawa Foundation and other industry and academic organizations. In 1999, Dr. Meng took leave from Stanford and founded Atheros Communications, Inc., which provides leading wireless system solutions for transparent connections of data, video, and voice communications. As a result of this effort, Dr. Meng was named one of the Top 10 Entrepreneurs in 2001 by Red Herring, Innovator of the Year in 2002 by MIT Sloan School eBA, the CIO 20/20 Vision Award in 2002, and the DEMO@15 World-Class Innovator Award in 2005. She returned to Stanford in 2000 to continue her research and teaching at the University. Dr. Meng's current research interests focus on circuit optimization, neural signal processing, and computation architectures for future scaled CMOS technology. She has given plenary talks at major conferences in the areas of signal processing and wireless communications. She is the author of one book, several book chapters, and over 200 technical articles in journals and conferences. Dr. Meng is a Fellow of the IEEE. She received her Ph.D. in EECS from the University of California at Berkeley in 1988.Host: Prof. Peter Beerel, x04481 ***A reception will follow the seminar at 4:00p.m.
