EE140 - Analog Integrated Circuits - 模拟集成电路--Prof.Robert W. Brodersen -University of California-Berkeley



Robert W. Brodersen Professor Emeritus-University of California-Berkeley

 Biography Robert W. Brodersen received a B.S. in both Electrical Engineering and Mathematics from California State Polytechnic University, Pomona, in 1966, and his M. S. and Ph.D. degrees in Electrical Engineering from MIT in 1968 and 1972, respectively. After spending three years with Texas Instruments in Dallas, he joined the faculty of the EECS Department at UC Berkeley in 1976; where he has pursued research in the areas of RF and digital wireless communications design, signal processing applications, and design methodologies. In 1994, he was the first holder of the John R. Whinnery Chair in Electrical Engineering and Computer Sciences. In 1998, he was instrumental in founding the Berkeley Wireless Research Center (BWRC), a consortium involving university researchers, industrial partners, and governmental agencies that is involved in all aspects of the design of highly integrated CMOS wireless systems. He retired in 2006 as Professor Emeritus but remains active at BWRC, where he is Co-Scientific Director, and at the Donald O. Pederson Center for Electronics Systems Design
