Abstract (abridged version of the ISSCC-2007 short course):

Frequency synthesizers are nowadays an integral part of digital, mixed-signal and RF system-on-chip solutions. As CMOS processes scale down, raw transistor performance and power consumption dramatically improve on one hand, but difficulties arise in implementing traditional phase-locked loop architectures on the other hand. This presentation will first review these challenges, such as low-voltage limitations, high gate and off-channel leakage, high flicker noise, highly nonlinear device characteristics, poor isolation from digital logic. Next, it will summarize some well-known workarounds. It will then focus on recently developed solutions that are amenable to nanometer scale technology.

Biography :

Robert Bogdan Staszewski received his PhD from the University of Texas at Dallas in 2002 for his research on RF frequency synthesis in digital deep-submicron CMOS. From 1991 to 1995, he worked at Alcatel Network Systems in Richardson, TX. He joined Texas Instruments in Dallas, TX, in 1995 where he holds an elected title of Distinguished Member of Technical Staff for his pioneering work on Digital RF Processor (DRP) architecture. He is currently a manager of DRP system and design development for transmitters and frequency synthesizers. He has authored and co-authored 50 IEEE journal and conference publications and holds 30 issued and 35 pending US patents.
