Composition, Structure, and Method for Fabrication of Tunable Inductors with Large Tunability

Tunability of conventional inductors is achieved either by mechanically tuning through bias magnet(s) or by adjusting the electric current in solenoids/electromagnets. These devices are typically bulky, slow, noisy, and inefficient. Various efforts have been devoted towards developing voltage tunable inductors that have large tunability and low energy consumption. Here we propose a voltage tunable inductor based on magnetoelectric effect and report several voltage tunable inductors with extremely large tunability. Meanwhile, we provide a guideline on material composition selection and structure design to achieve high tunability in inductors.
