摘要

一個高輸入阻抗、低輸出阻抗電壓模式萬用二階濾波器有三個輸入端與一個輸出端被提出。所提出的電路使用一個差動差分電流傳輸器(DDCC)，兩個差動電壓電流傳輸器(DVCCs)，一個第二代電流傳輸器(CCII)，三個接地電阻與兩個接地電容，且可以實現所有標準濾波功能，例如:低通、帶通、高通、帶拒、全通。電路具備以下特點:高輸入阻抗、低輸出阻抗、接地電阻與電容，角頻率與品質因素正交可調、不需要被動元件匹配條件。

Abstract

A high input and low output impedances voltage-mode universal biquadratic filter with three input terminals and one output terminal is presented. The proposed circuit uses one differential difference current conveyor (DDCC), two differential voltage current conveyors (DVCCs), one second-generation current conveyor (CCII), three grounded resistors and two grounded capacitors. The proposed circuit can realize all the standard filter functions, i.e. lowpass, bandpass, highpass, notch, and allpass from the same configuration. The proposed circuit offers the features of high input impedances, low output impedance, using only grounded resistors and capacitors, orthogonal controllability of resonance angular frequency and quality factor. It does not need passive components matching conditions.
