可适用于设计各种类型的SCF。

Abstract

A new technique for directly designing bilinear switched-capacitor filter using signal-flow graphs and the two-integrator-loop is described. This simple and flexible method is applicable to all types of SCFs. The resulting circuits have low sensitivities both to eleme-ntvalue variations and to parasitic capacitances.
