A software tool implementing cascaded SCF (Switched Capacitor Filter) is developed. A comprehensive procedure is described for the design of cascaded SCF, and some design considerations are discussed. In program several user-selectable filter approximation techniques, and two optimising methods which reduce the total capacitance are included. Analysis of the partial positive feedback and the effect of clock frequency to total capacitance are presented in detail. Two pratical examples are given to prove its validity in reducing the total capacitance. Developed tool can be used for general SCF generator.
