本文提出了一种新的阻抗匹配技术。它是用可变电感代替匹配网络中的固定电感，其值能够随负载阻抗而变化。在研究中，所考虑的固定电感是一个CMOS集成，而可调谐电感是基于一个新的压磁MEMS概念。首先给出了这种可调谐电感的理论模型，然后以电感值离散变化和连续变化两种不同的方式插入匹配网络中。将得到的匹配网络与固定电感匹配网络进行了比较，并给出了仿真结果，以验证所提出的方法，并评估每个匹配网络的匹配效率。(C)2010爱思唯尔有限公司版权所有。
We present in this paper a new technique of matching impedances. It consists in replacing a fixed inductor in a matching network by a variable one, and its value is able to change with the load impedance. In the study, the fixed inductance considered is a CMOS integrated one, while the tunable inductance is based on a new Piezomagnetic MEMS concept. A theoretical model of such a tunable inductor is first presented, and then inserted in a matching network in two different ways: inductance value varies either discretely or continuously. The obtained matching networks are compared with a fixed inductor matching network, and simulation results are presented and discussed to validate the presented method and to evaluate the matching efficiency of each matching network.
