A new method to analyze active switched-capacitor（SC） filter networks is proposed. It is based on the capacitance matrix C

charge transfer matrix D defined in this paper and well-known charge conservation principle. The method can not only analyze the SC network containg nonideal （single-pole model） operational amplifiers （OAs）

but also analyze the SC one with idel OAs. Using the method

closed formal expression of transfer functions for the first or second-order SC circuits with nonideal OAs can be obtained by manual operation-s. Besides

this approach is particularly suitable for computeraided analysis of active SC networks because it is very simple and normalize for us to write and find the equations.The exa-mle is given to illustrate the technique.
