一种用CC　Ⅱ设计连续时间滤波器的新方法

A Novel Approach to the Design of Continuous-Time Filters Based on CC Ⅱ

提出了一种用ＣＣⅡ设计连续时间滤波器的新方法，亦称为输入电压Ｖｉｎ的加权法．该方法的目标主要有两点：第一建立决定ＣＣⅡ滤波器极点的静网络；第二对此静网络注入加权输入信号而产生ＣＣⅡ滤彼器的零点．据此已设计出ＣＣⅡ的一阶和二阶连续时间滤波器．

novel approach to the design of continuous-time filters based on CC Ⅱ is presented. It can also be called a method with weighted input voltage signal Vin. There are two main points involved: the first is building up the dead network consisting of a series of building blocks so that the poles of the CC Ⅱ filter will be fixed, and the second is injecting weighted input signal Vin into the dead network so that the zeros of the CC Ⅱ filter are formed. Proper parameters and components for the resulting circuit are then selected. A family of the first-and second-order continuous-time filters have been successfully designed using CC Ⅱ.
