摘要
本文提出了一种新型的多功能滤波器 ,该滤波器仅由三个正电流传输器和五个无源器件构成 ,具有一个输入端和三个输出端 (SITO)。电路能实现低通、高通、带通、带阻及陷波等各种二阶滤波器功能 ,并具有输入阻抗低 ,输出阻抗高。不需要元件匹配 ,所有无源器件的灵敏度都非常低。
A new current-mode multifunction filter with a single input and three outputs employing only three positive CCⅡs and five passive elements is presented in the paper. The circuit can be used to realize second low-pass, high-pass, band-pass, all-pass and notch current-mode filter functions, in addition, with low input impedance and high output impedance. No component matching is required and the sensitivities of all passive devices are low. The corresponding PSPICE simulation frequency responses of second-order filter are also given.
