Abstract

The design procedures for integrated ladder filter design by operational simulation are regularized in terms of matrix operations. This analysis provides a systematic framework for the derivation of standard circuits such as leapfrog and coupled-biquad as well as several novel structures. Each circuit is seen to belong to a certain family, dependent on the type of matrix factorization used. A detailed comparison of the properties of the different structures is undertaken for a range of filter specifications, demonstrating that ladder filters offer good solutions to several difficult filtering problems. The methods are applicable to all active filter technologies including active-RC and switched capacitor
