With quality factors (Q) often-exceeding 10,000, vibrating micromechanical resonators have emerged as leading candidates for on-chip versions of high-Q resonators used in wireless communications systems. However, as in the case for transistors, extending the frequency of MEMS resonators generally entails scaling of resonator dimensions. Unfortunately, smaller size often coincides with lower-power handling capability and increased motional impedance. In this talk, I will introduce novel solid-state transduction techniques, present latest results on narrow-bandwidth parametric filters for frequency-agile radio receivers, discuss performance scaling of MEMS resonators to X-band frequencies and propose mechanisms for coupling MEMS resonators with silicon photonics, spin-torque oscillators and mechanical systems in the quantum regime.
Sunil received the B.S. and Ph.D. degrees from Cal in 1998 and 2004 respectively, in EECS. In October 2004, he joined the faculty of Cornell University, where he is presently an Assistant Professor in ECE. Sunil received the NSF CAREER Award in 2007 and the DARPA Young Faculty Award in 2008. His students have received the Best Student Paper Award at Ultrasonics 2009 and the Roger A. Haken Best Student Paper Award at IEDM 2007.
