The approach using the equivalent networks in the z-domain to analyze switched capacitor(SC)networks is very attractive.The proposed analysis method in this paper permits calculationof the frequency response of SC networks by means of the signal flow graph(SFG).In the first placethe equivalent network is derived by applying a group of basic building blocks which are obtained underthe consideration of generality and practicability.At the same time some specified transformationsare proposed,with which the basic building blocks can be greatly expanded to fit into direct use.Thesetransformations are also found to be useful in designing SC filters.The application of the well-knownSFG facilitates the derivation of discrete transfer functions.Furthermore the sensitivity of SC net-work can be calculated with a simple topological formula.The whole work can be done by inspec-tion;this is the highlight.
