摘　　要：提出了一种仅仅用第二代电流传送器(CCII+)实现的高阶电压模式低通滤波器,推导了系统的设计公式。设计了六阶Butterworth低通滤波器,并用PSPICE进行仿真分析。设计和仿真结果表明,该低通滤波器电路设计正确,电路结构简单,所用的元器件数目较少。A new method for the design of high-order voltage-mode low-pass filter based on CCII＋ was presented. The systematic design formula was derivatived. An sixth-order Butterworth low-pass filter was designed based on the proposed method and simulated in PSPICE. The simulation results show that the proposed method is feasible and the design circuits have characteristics of simple structure and less number of components.
