Realization of switched-capacitor voltage-wave filters containing zeros of transmission

This paper presents a novel approach to the design of filters which are suitable for eventual realization in monolithic form. The method is based on the use of sampled-data-analog signals and is related to the wave digital filter in its design techniques. Designs for a prototype sixth-order Chebyshev bandpass filter and a third-order low-pass filter, containing zeros of transmission at de and infinity, are presented. Good agreement with theory is obtained for the practical circuits realized in discrete form.
