摘要

本文介绍了一种广泛应用于模拟集成电路实现的全差动有源电感。由于在电感器的输入端连接了一个差分负电阻，因此保证了电感器的质量。单端有源电感存在非线性效应，因此需要采用差分拓扑来减小有源电感的非线性效应，避免偏置电流的浪费。仿真的差动有源电感具有很高的质量因数1340，工作频率为1.34 GHz。它可以很容易地调谐频率，适用于GSM 1800MHz应用。

Fully differential active inductor for CMOS active filter applications

A fully differential active inductor widely used in the implementation of analog integrated circuits is presented in this paper. The quality of the inductor is insured due to a differential negative resistor connected at the input of the inductor. Single ended active inductors present non-linear effects hence the need of using differential topology to reduce them and avoid the waste of biasing current. The simulated differential active inductor has a very high quality factor of 1340 and operates at 1.34 GHz. It can be easily tuned in frequency which is suitable for GSM 1800MHz applications.
