[Staff] Seminar Speaker today: Dr. Weinstein, MIT - videoconferenced from UW

[Theresa Garcia]

Please remind colleagues and students for today 2/13/12:

 

Center for Sensorimotor Neural Engineering

 

PRESENTS

 

"Active RF and mm-Wave MEMS Resonators 

Using Transistor Sensing"

 

Dana Weinstein, PhD

Finn Assistant Professor

Electrical Engineering and Computer Science

Massachusetts Institute of Technology



Dr. Weinstein will discuss the Resonant Body Transistor (RBT), which can be
integrated into a standard CMOS process for low power clock generation and
high-Q tank circuits. We recently demonstrated the first hybrid RF MEMS-CMOS
resonators in Si at the transistor level of IBM's 32nm SOI CMOS process,
without the need for any post-processing or packaging. The unreleased, Si
bulk acoustic resonators are driven capacitively using the thin gate
dielectric, and actively sensed using a body-contacted nFET incorporated
into the resonant cavity. FET sensing with the high fT, high performance
transistors in CMOS amplifies the mechanical signal before the presence of
parasitics. The resulting RF-MEMS resonators provide low power, low cost,
small footprint building blocks for on-chip signal generation and
processing.
