| 摘 要： | 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.

| Abstract: | It is a new approach to use current linear summers to directly realize ladder simulation filters.From viewpoint of generic OTA summation network,this paper derives a new type of ladder simulation filter structured by OTA summers and capacitors.Finally,an experiment of third order filter reveals the correctness of proposed theory. |

| Keywords: | active filter/ladder filter current linear summer |
