Adaptive Silicon: A Platform for Mixed Signal Processing in Low Power Applications




Growing complexity of SoC design for advance telecommunication and multimedia applications requires a new approach for joint optimization of analog and digital signal processing. Low power requirements and configurability are critical yet contradictory for many applications. On the other hand, recent advances in UDSM CMOS processes have brought about new set of design challenges and parameters such as leakage power and mask set complexity. In this talk, we present:

  • Some of the key challenges of mixed signal processing to design a low power and configurable SoC/SiP solution
  • The importance of cross disciplinary research in system optimization
  • Some design methodologies to achieve faster design cycle
As an example, wireless sensor networks will be discussed.


Dr. Ahmad R S Bahai is a Fellow and the Chief Technologist of National Semiconductor, an adjunct professor at UC Berkeley, and consulting professor at Stanford University.He received his MS degree from Imperial College, University of London in 1988 and Ph.D. degree from University of California at Berkeley in 1993, all in Electrical Engineering. He joined AT&T Bell Laboratories in 1993 where he was Technical Manager of Wireless Communication Group in Advanced Communications Technology Labs until 1997. He has been involved in R&D projects on major wireless systems and standards. He is one of the inventors of Multi-carrier CDMA (OFDM) concept and proposed the technology for high speed wireless data systems. He was the co-founder and CTO of ALGOREX Inc. His research interest includes adaptive signal processing and communication theory. He is the author of more than 50 papers and reports and his book on "Multi-carrier Digital Communications" is published by Kluwer/Plenum. Dr. Bahai holds ten patents in Communications and Signal Processing field and served0 as an editor of IEEE Communication Letters.
