用电流线性求和器直接实现梯型模拟滤波器是一种新的方法.本文从 OTA求和网络的一般概念出发,经过推导得到了用 OTA 器件构成的 OTA 求和器和 C 元件实现的梯型模拟滤波器.并用一个五阶滤波器的实例证明了理论的正确.
It is a new method to realize the ladder-type analog filter directly by using the current linearizer.This paper starts from the general concept of OTA summing network, and derives the ladder that the OTA sum- Type analog filter.An example of a fifth-order filter proves the theory is correct.
