Abstract:
1. A multilayer inductor comprising: a bottom magnetic layer including an external conductive pattern formed on a bottom surface thereof, the external conductive pattern including a plurality of signal/power contacts disposed at edges thereof and first and second inductor electrodes; a top magnetic layer including an external conductive pattern formed on a top surface thereof, the external conductive pattern including a plurality of signal/power contacts disposed at edges thereof and an inductor electrode contact; and a plurality of intermediate magnetic layers stacked between the bottom magnetic layer and the top magnetic layer, each intermediate magnetic layer including a plurality of signal/power contacts disposed at edges thereof and an inductor conductive pattern, each of the plurality of intermediate magnetic layer signal/power contacts electrically coupled to respective top and bottom magnetic layer signal/power contacts to form external signal/power routes between the top magnetic layer external conductive pattern and the bottom magnetic layer external conductive pattern, each of the intermediate magnetic layer inductor conductive patterns coupled to each other to form a spiral inductor element, the spiral inductor element coupled at a first end thereof to the top magnetic layer inductor electrode contact and at a second end thereof to the first inductor electrode, the top magnetic layer inductor electrode contact coupled to the second inductor electrode by an external inductor power route, comprising at least one of the external signal/power routes.
