Abstract:
The first part of this presentation will give a brief overview of research at
Connection One on RF, Analog and PMIC. This will be followed by a presentation
on Digital Linear Drop-out Regulators and the development of Power Management
IC. The development of multi-core highly integrated systems-on-a-chip has
created the need for small, fully integrated voltage regulators that operate on
a per-core basis. In order to maximize efficiency, most SOC's apply dynamic
voltage and frequency scaling (DVFS) on each block of the system to adjust the
power based on performance demands. Analog regulators are poorly suited to this
task as they are difficult to integrate on sub-micron processes, consume more
power, and require precision external capacitors to ensure stability. The
development of Digital LDO regulators is intended to address these drawbacks of
analog regulators.
Biography:
Dr. Sayfe Kiaei is has been with ASU since January 2001. He is a Professor and the Director of the Connection One Center (NSF I/UCRC Center), and Motorola Chair in Analog and RF Integrated Circuits. From 1993 to 2001, he was a Senior Member of Technical Staff with the Wireless Technology Center and Broadband Operations at Motorola where he was responsible for the development of RF & Transceiver Integrated Circuits, GPS RF IC, and Digital Subscriber Lines (DSL) transceivers. Before joining Motorola, Dr. Kiaei was a Professor at Oregon State University from 1987-1993 where he taught courses and performed research in digital communications, VLSI system design, advanced CMOS IC design, and wireless systems. Dr. has published more than 200 journal and conference papers and holds several patents. Dr. Kiaei is an IEEE Fellow and a member of IEEE Circuits and Systems Society, IEEE Solid State Circuits Society, and IEEE Communication Society. Dr. Kiaei has been organizer, on the tech!
nical program committee and/or chair of many conferences, including: RFIC, MTT,
ISCAS, and other international conferences.
