TITLE: Building Blocks for Silicon MEMS Timers
and Signal Processors

SPEAKER: Dr. Ashwin Seshia
Lecturer in MEMS and Fellow, Queens? College
Dept. of Engineering, University of Cambridge

Abstract:

This talk will introduce new building blocks and concepts for
silicon-on-insulator based MEMS resonator technology with a focus on
developments at the device and circuit levels. A comparison is drawn
between different transducer technologies and resonator topologies
with a view towards frequency scaling and power handling. Linear and
nonlinear circuit topologies are introduced for silicon
micromechanical resonator based oscillators with a view towards
compensating extremes of capacitive and motional parasitics inherent
in the hybrid integration of MEMS with CMOS while simultaneously
optimising for low phase noise and power dissipation. Scalable filter
topologies based on mechanically and electrically coupled resonant
modes in silicon microstructures are presented. Reverse-biased pn
junctions embedded in silicon microresonators are introduced as an
alternative, CMOS compatible transducer with beneficial scaling for
NEMS applications.

Short Bio:

Ashwin A. Seshia received the B.Tech. in engineering physics from IIT
? Bombay in 1996 and the M.S. and Ph.D. degrees from UC Berkeley in
electrical engineering in 1999 and 2002. His Ph.D. thesis
demonstrated the theory and operation of an integrated MEMS
resonant-frequency-shift output vibratory rate gyroscope. He is
presently a member of the faculty of the Cambridge University
Engineering Department where he is Lecturer in micro electromechanical
systems (MEMS), a Fellow of Queens? College and a member of the
Micromechanics and Nanoscience research groups. His research interests
include integrated micromechanical resonant structures for sensor and
timing applications, micromachined devices for in-vivo monitoring, and
biological sensor systems.
