A Systematic Design of Current-Mode Nth-Order CDBA-RC Universal Filter

摘要

摘要: 该文提出了利用电流差分缓冲放大器CDBA(the Current Differencing Buffered Amplifier)实现n阶电流模式滤波器的方法。基于信号流图给出了系统的设计公式，并举例设计了5阶Butterworth低通、高通及4阶Butterworth带通滤波器。PSPICE仿真表明，结果与理论分析完全吻合。该滤波器不仅电路结构简单，而且用的元件数目很少。

Abstract: A novel method for n-order current-mode filters using the Current Differencing Buffered Amplifier(CDBA) is presented. Based on the signal-flow-graph a systematic design formula is given in this papers. As examples, a new fifth-order butterworth low-pass, high-pass and fourth-order band-pass filters are realized. Simulation results from PSPICE are obtained to verify the theoretical analysis. The proposed filters have the characteristic of simple structure and less number of components.
