摘要

本論文使用差分差動電流傳輸器(DDCC)、電壓差動電流傳輸器(DVCC)與第二代電流傳輸器(CCII)提出三個多功/萬用電壓式濾波電路的設計。
首先，我們提出一個使用二個DDCCs，二個電容器及二個電阻器的三輸入、四輸出電壓式萬用二階濾波電路。此電路使用二個接地電容器，有利於電路積體化的實現；有非常低的主、被動敏感度；且均不需要任何阻抗匹配條件。
其次，我們提出一個使用一個DDCC，一個CCII，二個電容器及二個電阻器的單輸入三輸出電壓式多功二階濾波電路。此電路不需要任何阻抗匹配條件；使用二個接地電容器，有利於電路積體化的實現；有非常低的主、被動敏感度。
最後，我們提出一個使用一個DVCC，二個電容器及二個電阻器的單輸入單輸出電壓式低通二階濾波電路。此電路不需要任何阻抗匹配條件；使用二個接地電容器有利於電路積體化的實現；有非常低的主、被動敏感度。

Abstract
In this paper, three voltage-mode multifunction filters employing the differential difference current conveyors(DDCCs), the differential voltage current conveyor(DVCC) or the second-generation current conveyor(CCII) are presented.
First, we present a voltage-mode universal second-order filter with three inputs and four outputs employing two DDCCs, two capacitors and two resistors. The proposed filter has three following advantages：two grounded capacitors ideal for integration, very low active and passive sensitivities, and no requirement of critical component matching conditions.
Secondly, we present a voltage-mode multifunction second-order filter with single input and three outputs employing one DDCC, one CCII, two capacitors and two resistors. Three proposed filter has the following advantages：no requirement of critical component matching conditions, two grounded capacitors ideal for integration, and very low active and passive sensitivities.
Finally, we present a voltage-mode low-pass second-order filter with two input and one output employing one DVCC, two capacitors and two resistors. The proposed filter has the following advantages：no requirement of critical component matching conditions, two grounded capacitors ideal for integration, and very low active and passive sensitivities.
