摘要
本文提出了一个新的多功能有源C滤波器,该电路由四个OTA和两个电容器构成。给出了该电路所有可能的典型二阶滤波器实现,特别是,由该电路得到了三滤波输出功能。实验也证实了电路是正确的。
A new multifunction active-C filter is presented. The circuit is composed of four OTAs and two capacitors. All possible second-order filtering realizations for the proposed circuit are given. Especially, several realizations with three filtering outputs are obtained. The circuit is verified by the experiment with discrete elements.
