Abstract
A modulated inductance module includes an inductor including one or more electrical conductors disposed around a ferromagnetic ceramic element formed on a semiconductor die, wherein the inductor further has two or more metal oxides having fluctuations in metal-oxide compositional uniformity less than or equal to 1.50 mol % throughout said ceramic element, the ceramic element has crystalline grain structure having a diameter that is less than or equal to 1.5× a mean grain diameter, and the semiconductor die contains active semiconductor switches or rectifying components that are in electrical communication with the one or more electrical conductors of the inductor.
