运用信号流图和双积分器结构
可直接设计具有双线性传递函数的SCF。本设计方法
简明直观
所得电路对元件值变化和分布电容的灵敏度都较低
可适用于设计各种类型的SCF。
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.
