摘要

在本論文中將提出一個新的電壓模式一階全通濾波器，此電路使用一個差動電壓電流傳輸器(DVCC)、一個電容及兩個電阻來實現所需之濾波功能，而此濾波器可同時實現兩種一階濾波功能，分別為低通濾波及全通濾波，並且具備以下特性，使用較少之主動及被動元件、全電容皆接地、用作低通濾波時不須阻抗匹配。

本論文藉由Hspice的模擬結果與Matlab的理論分析來驗證此電路，其結果與理論相近。

In this paper, we will present a new voltage-mode first-order filter circuit. This circuit using one differential voltage current conveyor (DVCC), one capacitor and two resistors. It can realize first-order filter functions which are lowpass and allpass responses. This filter have some characteristic, like: use less active component and passive component, grounded capacitor, no impedance matching required when used as lowpass filter.

We use HSPICE and MATLAB to simulate this filter circuit. The results are close to theoretical predictions.
