The authors present a symbolic switched capacitor (SC) circuit analysis program, called SSCNAP, which was developed on a microcomputer. The program is based on a method that uses numerical algorithms at all stages. Partially or totally symbolic transfer functions, large-change sensitivities, relative sensitivities, and poles and their sensitivities for arbitrary K-phase SC circuits can be obtained using SSCNAP. No topological or duty-cycle constraints have been imposed on the circuits. The discussion is limited to ideal SC circuits that do not contain any resistances.>
