摘要

在本論文中提出了一個新型高輸入阻抗電壓式三輸入六輸出萬用二階濾波器。此濾波器使用三個正型差動差分電流傳輸器(differential difference current conveyor, DDCCs)、兩個接地電容器和三個電阻器。所提出的電路可以實現所有標準濾波功能（低通、高通、帶通、帶拒和全通）。此電路享有：一、使用兩個接地電容器；二、高輸入阻抗；三、主動和被動元件都有低靈敏度特性。HSPICE的模擬結果證實了這項理論分析。

This paper presents a new high input impedance voltage-mode universal biquadratic filter with three inputs and six outputs using three plus-type differential difference current conveyors (DDCCs), two grounded capacitors, and three resistors. The proposed circuit can realize all the standard filter functions (low-pass, high-pass, band-pass, notch, and all-pass). Moreover, the circuit enjoys (i) the employment of two grounded capacitors, (ii) high input impedance and (iii) low active and passive sensitivity performance. HSPICE simulation results confirm the theoretical analysis
