摘要

在本論文中，提出一個新的三輸入一輸出的電壓式二階萬用濾波器。
文中所提到的電路結構使用了兩個負型的電壓差動電流傳輸器(DVCCs)和兩個接地電容器以及兩個電阻器。它可產生以下功能：實現各種種類的濾波器，指的是高通、帶通、低通、帶距、全通等濾波器，不需要考慮元件的匹配問題，只採用接地電容器以及其主動和被動元件靈敏度值很低。

This paper presents a new voltage-mode universal biquadratic filter with three inputs and one output. The proposed circuit employs two minus-type differential voltage current conveyors (DVCCs), two grounded capacitors and two resistors can offer the following features: realization of all the standard filter functions, that is, high-pass, band-pass, low-pass, notch, and all-pass filters, no requirements for component matching condition, the use of only grounded capacitors and low active and passive sensitivities.
