Abstract

A new biquadratic universal filter configuration realizing second-order low-pass, band-pass, and high-pass filters using a single current conveyor is proposed. Using this configuration high-pass, low-pass and band-pass filters can be realized with little modifications. The circuit employs a second-generation current conveyor (CCII+), and only four passive components. Since the current conveyor is a high performance active element, the circuit proposed is suitable for wide band applications. The derived filters can be easily cascaded and use reduced number of passive components compared to previously reported counterparts. To illustrate the design possibilities provided by the introduced circuit, current mode multifunction filters are constructed and tested.

一种新颖的多输入单输出滤波器，减少了无源元件的数量

提出了一种新的双二次型通用滤波器结构，利用单一电流输送机实现二阶低通、带通和高通滤波器。使用这种配置可以实现高通、低通和带通滤波器，修改很少。该电路采用第二代电流传送带(CCII+)，只有四个无源元件。由于电流输送器是一种高性能有源元件，因此所提出的电路适用于宽带应用。与之前报道的滤波器相比，衍生滤波器可以很容易地级联，并且使用的无源元件数量减少。为了说明所介绍的电路提供的设计可能性，构建并测试了电流模式多功能滤波器。
