Abstract:
A magnetic core is provided for an integrated circuit, the magnetic core comprising: a plurality of layers of magnetically functional material; a plurality of layers of a first insulating material; and at least one layer of an secondary insulating material; wherein layers of the first insulating material are interposed between layers of the magnetically functional material to form subsections of the magnetic core, and the at least one layer of second insulating material is interposed between adjacent subsections.
