Description

Abstract : An analog/mixed-signal designer encounters time varying circuits everywhere - sample-and-holds, chopper stabilised amplifiers, mixers, switched-capacitor amplifiers and filters, discrete and continuous-time delta sigma modulators, N-path filters. The analysis of signals and noise in these circuits is often associated with messy mathematics and algebra. This talk aims to demystify linear (periodically) time varying circuits. Starting from first principles, intuition behind various aspects of time-varying circuits and systems will be given. This intuition is illustrated with case studies of practical circuits and systems, like chopper-stabilised amplifiers and continuous-time delta-sigma modulators.
