Description

This course examines topics related to the design and implementation of analog microelectronic circuits. The topics include an introduction to noise and distortion in electronic circuits, feedback, analysis and design of biasing circuits, operational amplifiers and comparators, references, analog-to-digital converters, digital-to-analog converters, power amplifiers, mixers, signal generators and wave shaping, circuits for modulation and demodulation, phase-locked loops, and an introduction to analog filter design. Aspects of component modelling are also covered. This course builds on material in earlier circuits and electronics courses, including ELEC 221, ELEC 252, and ELEC 353, as well as concepts related to signals and systems in ELEC 323.
