My area of interest is in analog integrated circuits for high speed data communications. My research is part of InfoPad's RF project dealing with the downlink reception. A DS-CDMA demodulator prototype chip has been fabricated to demonstrate a passive analog integration technique that makes it possible to perform a high-speed correlation with minimal power. The prototype chip dissipates 75mW when operating at 128MHz. My advisor is Paul Gray at the University of California at Berkeley.
