Switched-Capacitor Filter Optimization with Respect to Switch On-State Resistance and Features of Real Operational Amplifiers

Popis výsledku v původním jazyce

The paper describes the optimization of a switched-capacitor filter. The aim of the optimization is to obtain a required magnitude frequency response of the filter by means of the differential evolution. An optimal dynamic range is to be achieved too. The optimization takes into account both one of the features of real switches - on-state resistance, and the features of real operational amplifiers - finite voltage gain and finite unity-gain bandwidth. Other main features of real operational amplifiers (input and output resistance) have small effect. The filter with ideal switches and operational amplifiers is designed by the usual way at first. The analysis of this filter with real switches and operational amplifiers shows a significant difference between its magnitude frequency response and the one with ideal components. Thus, the optimization is applied to finding component values for the response to be as similar to the one with ideal components as possible.
