Abstract
A compact systematic analysis method to obtain closed-form expressions for the z -domain transfer functions of switched-capacitor (SC) circuits with finite gain-bandwidth (GB)-product op amps is presented. This procedure allows exact frequency analysis of general SC circuits without imposing any restriction in the ratio between GB and clock frequencies and, is based on the modeling of each op amp by a suitable SC subcircuit with its own clock frequency, which is made to tend toward infinity
