Integrated Tunable Magnetoelectric RF Inductors

A great challenge in power/RF electronics has been achieving integrated magnetic inductors with high quality factor (Q-factor) and high inductance density at gigahertz frequencies. In this article, integrated solenoid magnetoelectric inductors based on FeGaB/Al2O3 multilayer as the magnetic core are designed to operate at high gigahertz frequencies, high Q-factor, and inductance tunability. A high self-resonant frequency of >3 GHz with a flat...
