摘要
本文提出了采用运算跨导放大器(OTA)和电容实现电气可控高阶全极点低通滤波器的设计方法.基于对无源LC梯型网络的模拟,导出了OTA-C型全极点低通滤波器的一般结构。该结构的特点是:结构简单,元件数目少,电控方便。
This paper presents a design method ot electronically controlted high-order all-pole lowpass filters using operational transconductance ampliziers(OTA) and capacitor .Basing on the simulation for the passive LC Ladder structure, we derive a general structure of all-pole lowpass fillers with OTA-C. The features of this structure are a simple structure ,a small numher of components and el(?)tronically controlled ability.
