Integrated Circuits for Communications

Analysis and design of electronic circuits for communication systems, with an emphasis on integrated circuits for wireless communication systems. Two-port networks are studied in detail, including feedback and stability, S-parameter analysis, and optimal gain and noise performance. Transmission lines, the Smith Chart, and lumped and distributed matching techniques are covered. Analysis of noise and distortion in amplifiers and mixers with application to radio receiver design. Power amplifier design with application to wireless radio transmitters. Radio-frequency mixers, oscillators, phase-locked loops, modulators, and demodulators.

Course objectives: To establish the principles involved in realizing electronic circuit functions for communication applications and to gain design experience in realizing appropriate specifications.


Ali Niknejad, Professor

Ali M. Niknejad received the B.S.E.E. degree from the University of California, Los Angeles, in 1994, and the M.S. and Ph.D. degrees in electrical engineering from the University of California, Berkeley, in 1997 and 2000. From 2000 to 2002, he worked at Silicon Laboratories in Austin, TX, where he was involved with the design and research of CMOS RF integrated circuits and devices for wireless communication applications. Currently, he is a professor in the EECS department at UC Berkeley. He is a co-director of the Berkeley Wireless Research Center (BWRC) and also the co-director of the BSIM Research Group. He served as an associate editor of the IEEE Journal of Solid-State Circuits and on the TPC for the International Solid-State Circuits Conference (ISSCC) and the Custom Integrated Circuits Conference (CICC). His current research interests lie in the areas of RF/microwave and mm-wave integrated circuits, particularly as applied to wireless communications and medical applications. His interests also include device modeling and numerical techniques in electromagnetics.
