摘要/Abstract

摘要：提出了一种基于多输出电流控制传送器（Multiple-Output Current Controlled Conveyor II,CCCII±）的n阶多环反馈(Multiple-Loop Feedback,简称MF)电流模式低通滤波器的系统设计方法.用该方法可产生出多种不同结构的n阶低通滤波器，所有n阶滤波器均由n个CCCII±及n个接地电容组成，便于集成实现，并给出了4阶低通滤波器的设计例子和多参数灵敏度计算机仿真结果.

Abstract: A systematic method of designing nth-order multiple-loop feedback current-mode low-pass filter based on multiple-output current controlled conveyor（CCCII±）is presented.Different kinds of nth-order low-pass filter structure can be obtained by this method.The proposed nth-order filter is constructed by n CCCIIs and n grounded capacitors.and is integrated conveniently for all the capacitors grounded.Design example of 4th-order lowpass filter and computer simulation results of multiple-parameter sensitivity are also provided.
