An Alternative Vision of SC-filter Synthesis Based on Operational Simulation Method

Abstract

the solution of the SC-filter realization problem is the paper scope. A simple practical approach that doesn’t need an additional prototype circuit transformation is considered. The idea is to realize the transfer function zero as a parallel connection of the differentiator and integrator. The realized SC-filter will have a least sensitivity in a comparison with other approaches because of the "cancellation effect" absence, but needs one extra OpA for each zero of the transfer functions. The analysis of the circuits worked out by means of continuant algebra and simulations confirm the validity of the proposed approach.
