摘要

本文提出一种用负阻抗变换器（NIC）实现的新的梯形模拟有源滤波器

其突出优点是电路稳定、动态范围大、容易调整

可实现高质量有源RC滤波器。文中揭示了单运NIC稳定性和动态范围大的条件是一致的

发现影响单运放NIC稳定性的一个本质原因是自锁。

Abstract

In this paper

a new kind of actve filters of ladder simulation using negative impedance converters （NIC） is given. They have such outstanding merits as stability of circuits

large dynamic range

easiness of regulation. They can be made into high quality active RC filter. It is shown that the conditions for stability and for large dynamic range are consistent and the essential factor affecting the stability of NIC is self locking.
