Abstract

Recent developments of digitally-intensive radio architectures indicate that future radio transceivers will not only become software-defined or highly reconfigurable but also follow similar computing model used in today’s digital processors. Application specific instruction-set processor (ASIP), increasingly used for media processing, appears to be the best choice of implementing such architectures. The relentless trend towards the full radio integration in nanometer-scale CMOS has already transformed RF functionality, traditionally implemented using analog RF circuits, into all-digital and digitally-intensive architectures, with only a few analog transistors remaining. When contrasted with the traditional RF circuits, which suffer from numerous issues in modern digital CMOS technology, the digital gates and memory are almost free and computationally powerful and are now being used to greatly enhance the radio performance.

Biography

Robert Bogdan Staszewski received the BSEE (summa cum laude), MSEE and PhD degrees from the University of Texas at Dallas in 1991, 1992 and 2002, respectively. From 1991 to 1995 he was with Alcatel Network Systems in Richardson, TX, working on Sonnet cross-connect systems for fiber optics communications. He joined Texas Instruments in Dallas, TX, in 1995 where he is currently a Distinguished Member of Technical Staff. Between 1995 and 1999, he has been engaged in advanced CMOS read channel development for hard disk drives. In 1999 he co-started a Digital RF Processor (DRPTM) group within Texas Instruments with a mission to invent new digitally-intensive approaches to traditional RF functions for integrated radios in deep-submicron CMOS processes. Dr. Staszewski currently serves as a CTO of the DRP group. He has authored and co-authored one book, 90 journal and conference publications, and holds 50 issued and 50 pending US patents. His research interests include nanoscale CMOS architectures and circuits for frequency synthesizers, transmitters and receivers.
