Ruai Y. Yu received the B.S. degree in electrical engineering from San Francisco State University in 1988 and the M. S. and Ph. D. degrees, both in electrical engineering, from the University of California at Santa Barbara (UCSB) in 1991 and 1994. From 1988 to 1989, he was a research engineer at Ampex Corporation where he was engaged in the research and development of advanced equalization schemes for high speed digital recording channels. While he was a graduate student at UCSB, he worked on monolithic and hybrid integrated circuits for microwave/millimeter-wave instrumentation and active probe systems for on-wafer microwave/millimeter-wave waveform and network measurements. He is currently a member of technical staff in the High Speed Circuits Department, Rockwell International Science Center, where he is involved in the design and packaging of the MMIC’s for high bit rate optical transmission systems.
