电流传送器构成通用的有源滤波网络

UNIVERSAL ACTIVE FILTER NETWORK EMPLOYING CURRENT CONVEYOR

介绍了一种利用第二代电流传送器构成通用的电流型有源滤波网络的新型结构,这种网络只需对其无源元件稍加修改便可获得各种所需的二阶有源滤波器.并通过实例说明了利用该新型网络能系统地导出各类二阶有源滤波器的电流传递函数。

This paper presents a new universal active filter network. Based on the network,it is easy to produce all the standard second- order filter sections, only though varying its positive elements. Exampls are also preseted to show that,using the network, all filtering current transfer function realizations can be systematically derived.
