Abstract
Recent developments of digitally-intensive radio architectures indicate that future radio frequency (RF) 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
R. Bogdan Staszewski received BSEE (summa cum laude), MSEE and PhD from University of Texas at Dallas, USA, in 1991, 1992 and 2002, respectively. From 1991 to 1995 he was with Alcatel in Richardson, Texas. He joined Texas Instruments in Dallas, Texas in 1995. In 1999 he co-started a Digital RF Processor (DRPTM) group with a mission to invent new digitally-intensive approaches to traditional RF functions. Dr. Staszewski has served as a CTO of the DRP group between 2007 and 2009. Since July 2009 he is Associate Professor at Delft University of Technology in the Netherlands. He has co-authored two books, four book chapters, 130 journal and conference publications, and holds 90 issued and 40 pending US patents. His research interests include nanoscale CMOS architectures and circuits for frequency synthesizers, transmitters and receivers. He is an IEEE Fellow.
