Abstract:
A circuit board comprising:a laminate of a power layer, a ground layer, and a plurality of signal layers, each of said power, ground, and signal layers being separated from an adjacent one of said power, ground and signal layers by an insulation layer, wherein at least two of said signal layers each comprises plural separate segments;plural electrically conductive first vias through the insulation layer between said at least two signal layers, each of said first vias connecting one of said segments in one of said at least two signal layers to one of said segments in another of said at least two signal layers, wherein a series connection of said plural first vias and plural said segments in each of said at least two signal layers is a continuous coil; anda second via with an inductor therein that connects said continuous coil to a contact pad on the circuit board and an electrically conductive third via that connects said continuous coil to said power layer.
