About the Speaker:

Dr. Sameer Sonkusale is an Assistant Professor of Electrical and 
Computer Engineering at Tufts University, Medford, MA. He received 
his MS and PhD in Electrical Engineering from University of 
Pennsylvania in 2003. Prior to coming to Tufts, Dr. Sonkusale held a 
similar position at Texas A&M University from 2002-2004. His research 
interests are in the broad area of analog and mixed signal VLSI 
design in emerging technologies for sensors and instrumentation. In 
his prior avatar, he was interested in designing circuits for 
communication applications.

About the Lecture:

The talk will focus on novel approaches to improve the sensitivity 
and selectivity of  chemical sensors through integrated circuit 
implementations of advanced signal processing algorithms in silicon. 
Most solid state sensors fabricated using traditional CMOS technology 
can even surpass the performances
of their expensive counterparts through integration of 
computationally intensive algorithms along with sensors for signal 
conditioning, feature extraction, calibration, and built-in self test 
on the same silicon substrate.  The entire system could be 
implemented either as a system on chip (SoC) or a system in package 
(SiP).  Two vehicles for chemical sensing will be presented as a 
proof of concept. One technique uses a capacitance based particle 
sensing methodology which has been made highly selective through the 
use of radio frequency excitations covering a wide frequency range. 
The other technique uses a novel concept called "fluctuation enhanced 
sensing" to improve the selectivity of traditional gas sensors.
