ABSTRACT:
A very, very low resistance micro-electromechanical system (MEMS) inductor, which provides resistance in the single-digit milliohm range, is formed by utilizing a single thick wide loop of metal formed around a magnetic core structure. The magnetic core structure, in turn, can utilize a laminated Ni—Fe structure that has an easy axis and a hard axis.
