Abstract

An integrated circuit and method of manufacturing therefor. In one embodiment, the integrated circuit includes a substrate with an insulator and a capacitor formed over the substrate. The integrated circuit further includes an adhesive formed over the insulator. The integrated circuit still further includes a micromagnetic device. The micromagnetic device includes a ferromagnetic core formed over the adhesive. The adhesive forms a bond between the insulator and the ferromagnetic core to secure the ferromagnetic core to the substrate. The micromagnetic device also includes at least one winding, located proximate the ferromagnetic core, to impart a desired magnetic property to the ferromagnetic core. The micromagnetic device is electrically coupled to the capacitor.
