本論文提出一個以三個正型差分差動電流傳輸器(DDCCs)、兩個接地電容器和兩個電阻器所組成的一輸入五輸出高輸入阻抗電壓模式萬用二階濾波器。本電路有以下特點：只使用接地電容器、高輸入阻抗，以及可實現所有標準濾波器功能，例如，高通、帶通、低通、帶拒和全通濾波器，並且不受到阻抗匹配的限制。

A new single input and five output voltage-mode universal biquadratic filter with high-input impedance using three plus-type differential difference current conveyors (DDCCs), two grounded capacitors and two resistors is presented. The proposed circuit offers the following features: realization of all the standard filter functions, that is, high-pass, band-pass, low-pass, notch, and all-pass filters simultaneously without component matching conditions, the use of only grounded capacitors and high-input impedance.
