Direct Analysis of Multiphase Switched-Capacitor Networks Using Signal-Flow Graphs

A by-inspection analysis method for multiphase switcbedcapacitor (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 systems). It may also serve as a tool for the symbolic computer analysis and for the synthesis of general multiphase SC nehvorks. Illustrative examples demonstrate the simplicity and efficiency of the method.
