Abstract

A general topology of continuous-time active-RC filter is presented. The model includes all possible active-RC filter structures as particular cases and allows us to analyze them using a unified algebraic formalism. This makes it suitable for use in computer-aided analysis and design of active-RC filters. By its construction, the model takes into account finite DC gain and finite bandwidth as well as the non-zero output resistance of operational amplifiers. A few examples of applications of the presented model for the analysis of active-RC filters are given and potential applications for filter optimization are discussed.
