Direct analysis of multiphase switched-capacitor networks using signal-flow graphs

A by-inspection analysis method for multiphase switched-capacitor (SC) networks using signal-flow-graph (SFG) techniques is presented. The method is quite general; no restrictions on the networks are required. It is also very simple and direct in the sense that it allows an immediate, by-inspection derivation of the SFG merely on the basis of a given SC network. The method is primarily useful for the hand analysis and design of small and medium-size SC networks (e.g. building blocks of modular SC system). It may also serve as a tool for symbolic computer analysis and for the synthesis of general multiphase SC networks. Illustrative examples demonstrate the simplicity and efficiency of the method
