摘要

本篇論文提出了一具備高輸入阻抗、三個輸入端與五個輸出端的電壓模式泛用二階濾波器。此電路使用了三個差動電壓電流傳輸器(DVCCs)、一個第二代電流傳輸器(CCII)、三個接地電阻以及兩個接地電容。此電路能呈現出所有標準濾波功能，例如:低通、帶通、高通、帶拒與全通，且沒有元件匹配的限制。所提出的電路具備以下特點：高輸入阻抗、接地電容，角頻率與品質因素正交可調。

A high input impedance voltage-mode universal biquadratic filter with three input terminals and five output terminals is presented. The proposed circuit uses three 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, namely, lowpass, bandpass, highpass, notch and allpass without component matching conditions. The proposed circuit still offers the features of high input impedance, using only grounded capacitors, and orthogonal controllability of resonance angular frequency and quality factor.
