I'm a graduate student researcher in electrical engineering at the University of California at Berkeley.

I'm working on a high-speed dual-mode sigma-delta A/D converter for fully-integrated, multistandard RF receivers. Adaptability to both cellular and cordless communications standards is achieved by using a single ADC with programmable dynamic-range and bandwidth. My advisor is Professor Paul R. Gray. We are collaborating in this research with Professor Bernhard Boser.
