A computer-oriented method for exact frequency-domain analysis of nonideal switched-capacitor (SC) networks is presented. It is based on the utilization of an SC macromodel for the operational amplifiers (op amps) when its own clock frequency tends to infinitum. This method extends the capability of a similarly based one previously developed by the authors. Its application allows the z-domain transfer functions, the complete frequency spectrum, and response sensitivities to element changes to be obtained in a quite inexpensive way. It basically consists of closed-form manipulations over a reduced set of matrices derived by means of an adaptation of the two-graph modified nodal approach. Therefore, no additional matrices need to be obtained. Also, the need for explicit numerical integration in each phase is eliminated because it is included in the procedure. This technique not only reduces the computational cost of spectral analysis of SC networks, but also makes exact sensitivity calculation very easy when compared with previously published works
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

This method allows exact frequential analysis of a general class of SC circuits, without imposing any restriction in the ratio between GB and clock frequencies.
