摘要

本文介绍了两种仅用运算放大器(OA)和运算跨导放大器(OTA)实现的二阶低通滤波器。该电路不需要额外的无源元件，这使得它们适合集成电路(IC)的实现，并减少了芯片面积。过滤器参数可独立调节。仿真结果验证了理论的正确性。

Active lowpass filters without external passive components realized with OTA and Op amps

This paper presents two second-order lowpass filters realized with operational amplifiers (OA) and operational transconductance amplifiers (OTA) only. The circuits do not require additional passive components, which makes them suitable for integrated circuit (IC) implementation and reduces chip area. The filter parameters can be adjusted independently. Simulation results are included to verify theory.
