Computer-aided analysis of switched-capacitor filters

A technique is presented for computer-aided analysis for a class of switched-capacitor (SC) circuits that can be partitioned into elementary subnetworks. This new approach is distinctly different from other published techniques, because, rather than striving for complete generality, it incorporates features that are specifically needed in practical SC circuits in order to produce an efficient algorithm for machine computation. The analysis technique is formulated in the time and frequency domains and a user-oriented program (scAP) is described that implements this technique. In addition, sensitivity analysis is also formulated for this new approach.
