摘要
本文给出的OTA浮地模拟电感结构简单容易实现。最大优点是通过控制OTA的偏置电流I_(ABC)可以实现浮地电感量的连续调节。本文给出的电路可以实现浮地电感单片集成电路。文章最后给出了该电感组成的柯尔型低通滤波器的实例。理论与实验相一致。
The structure of a new OTA floating inductance simulator is given. It is simple and can be realized very easily. Its most advantage is that the volume of the inductor can be adjusted continuously by changing the bias current IABC. The curcuit given in this paper can be made with the monolithic integrated circuit. A kind of Caure low-pass filter is realized by using this kind of floating inductor and it is shown that the experimental results are in good agreement with the theoretical design.
