EE W242AIntegrated 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.
