Computer oriented formulation of equations and analysis of switched-capacitor networks

The computational aspects of the analysis of switched-capacitor (SC) networks having ideal elements and an arbitrary number of phases are discussed. In each phase, a special two-graph preprocessing step eliminates all switches and topologically compresses the resulting matrices to the minimum. Subsequently, a new solution method reduces the problem to the solution of the compressed system. in a single phase. The majority of steps are transferred into preprocessing and done only once. A summary of various analyses, available in the WATSCAD program, is presented as well.
