Abstract:
Broadcom is one of the largest fabless semiconductor suppliers focusing on both wired and
wireless communications. The rapid growth of internet traffic is creating new opportunities
for Broadcom and its analog designers. For example, due to high speed serial links transition
to 40Gbps and 100Gbps data rates, multi-GHz ADCs have become a hot research topic. This
talk will provide an overview of recent advances and ongoing research in multi-GHz ADC-based
receivers, various architectures and the design of its key blocks.

Biography:
Afshin Momtaz received the M.S.E.E degree from UCLA, and the Ph.D. degree from UC Irvine.
From 1992 to 1998, he was with Western Digital and Adaptec corporations where he designed
disk-drive read channel and fiber channel transceiver chips. In 1998, he joined the NewPort
Communications, where he was involved with design of various OC48 and OC192/10GE CMOS
transceivers. Since the acquisition of NewPort Communications by Broadcom in 2000, he has
been also focusing on 20 and 40Gbps equalizer designs for optical, copper and backplane
applications. He is currently a engineering director of the Analog and Mixed Signal group. Dr.
Momtaz has authored/coauthored more than fifteen journal/conference papers. He has more
than 70 U.S. patents issued in the area of multi GHz mixed signal circuits and systems.
