He has also contributed to the development of PLLs in the StrongARM, Alpha and AMD K6/K7/K8 microprocessors. Since 1994, he has been a Professor of Electrical Engineering at Stanford University where his research focus has been on gigahertz-speed wireline and wireless integrated circuits built in conventional silicon technologies, particularly CMOS.

He has twice received the "Best Paper" award at the International Solid-State Circuits Conference, co-authored a "Best Student Paper" at ISSCC, was awarded the Best Paper prize at CICC, and is a Packard Foundation Fellowship recipient.

He is an IEEE Distinguished Lecturer of the Solid-State Circuits Society, and has been a DL of the IEEE Microwave Society as well. He holds 43 U.S. patents and authored The Design of CMOS Radio-Frequency Integrated Circuits (now in its second edition), and Planar Microwave Engineering, both with Cambridge University Press. He is a co-author of four additional books on RF circuit design, and also cofounded Matrix Semiconductor (acquired by Sandisk in 2006). He is the founder of ZeroG Wireless.
