It is well known that Integrated circuit (IC) process scaling has worked wonders for the capabilities of electronic systems. Today's digital ICs are orders of magnitude better than before. However, scaling has placed tremendous performance demands and challenges on analog circuits that interface between the digital ICs and the real world. Particularly challenging are problems posed by reduced supply voltages, increased process variability and device non-linearity.
Traditional design approaches based on engineer experience and careful, painstaking circuit optimization are proving incapable of meeting these challenges. We have been developing an alternative approach that achieves desired circuit performance even from error-prone analog circuit blocks implemented in scaled processes. The approach employs algorithmic techniques derived from signal processing and communication theoretic principles and implemented in inexpensive digital logic to overcome circuit imperfections.
This talk will present a choice selection of digital architectures and techniques to improve the performance of several critical blocks spanning the gamut of analog and mixed signal circuits. Particular attention will be paid to techniques targeting important problems such as power amplifier efficiency.
Dr. Sudhakar Pamarti is an assistant professor of electrical engineering at the University of California, Los Angeles, where he teaches and conducts research in the fields of mixed-signal circuit design and signal processing. Dr. Pamarti received the M.S. and the Ph.D. degrees in electrical engineering from the University of California at San Diego in 1999 and 2003, respectively, and the Bachelor of Technology degree in electronics and electrical communications engineering from the Indian Institute of Technology, Kharagpur in 1995. Prior to joining UCLA, he has worked at Rambus Inc. ('03-`05) and Hughes Software Systems ('95-`97) developing high speed I/O circuits and embedded software and firmware for a wireless-in-local-loop communication system respectively. Dr. Pamarti has served on the editorial board of the IEEE Transactions on Circuits and Systems II and is a recipient of the U.S. National Science Foundation's CAREER award.
