Abstract:
1. A magnetic core element of an integrated circuit inductor structure, the magnetic core element comprising: a bottom segmented magnetic core element that includes a plurality of spaced-apart bottom element laminations, each bottom element lamination having a first edge that is parallel to an edge of a first adjacent bottom element lamination and a second edge that is parallel to an edge of a second adjacent bottom element lamination; and a top segmented magnetic core element that includes a plurality of spaced-apart top element laminations, each top element lamination having a first edge that is parallel to an edge of a first adjacent top element lamination and a second edge that is parallel to an edge of a second adjacent top element lamination, the bottom and top segmented magnetic core elements being disposed with respect to each other so as to surround a conductive inductor coil that is separated from the bottom and top magnetic core elements by intervening dielectric material, wherein at least one bottom element lamination combines with a corresponding top element lamination to provide a magnetic core lamination in which at least a portion of the magnetic fluxes that flow in the magnetic core lamination when a current is passed through the inductor coil cancel each other.
