this page is a summary of the projects and students under paul gray and robert meyer at the university of california at berkeley.

the focus of our group is designing analog circuits for high integration. we have emphasized analog cmos design techniques because an increasing portion of today's integrated circuit functionality is being performed in the digital domain by vlsi circuits implemented in a cmos technology. achieving high integration requires both all the analog signal processing and the associated analog-to-digital interface to be built with the same technology as the digital circuits.

a large effort is also being expended on the design of high-frequency, bicmos and bipolar integrated circuits. currently work is being done on power amplifiers, mixers, and low-noise pre-amplifiers.
