摘要

在本論文中，提出一個以三個差動差分電流傳輸器(DDCC)、四個電阻以及兩個接地電容所組成之高輸入阻抗電壓模式可調萬用二階濾波器。所提出之電路具備以下的特點：使用接地電容、具備高輸入阻抗、諧振角頻率與品質因素為正交可調、以及可實現全部標準濾波器之功能，所提出之電路可同時具有低通、帶通、高通、帶拒以及全通之濾波輸出信號；此外也具有低靈敏度的特性。

In this paper, a new high input impedance voltage-mode universal biquadratic filter with Three input terminals and Seven output terminals is presented. The proposed circuit uses three differential difference current conveyors (DDCCs), four resistors and two grounded capacitors. The proposed circuit can realize all the standard filter functions: lowpass, bandpass, highpass, notch and allpass, simultaneously. The proposed circuit offers the features of high input impedance, using only grounded capacitors, and orthogonal controllability of resonance angular frequency and quality factor.
