An equivalent circuit approach to the computer-aided analysis of switched capacitor circuits

Abstract

An equivalent circuit approach to the computer-aided analysis of switched capacitor circuits is described. The exact transfer functions of the circuits under continuous inputs are computed via the simulation of an equivalent circuit in the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">z</tex> domain. Several switched capacitor filter circuits are discussed and their simulated results are compared with measured data.
