Abstract:
A toroid inductor includes a plurality of first turns configured in a first ring shape and a plurality of second turns configured in a second ring shape. The plurality of first turns includes a plurality of first upper interconnects, a plurality of first lower interconnects, and a plurality of first vias coupled to the plurality of first upper interconnects and to the plurality of first lower interconnects. The plurality of second turns is at least partially intertwined with the plurality of first turns. The plurality of second turns includes a plurality of second upper interconnects, a plurality of second lower interconnects, and a plurality of second vias coupled to the plurality of second upper interconnects and to the plurality of second lower interconnects.
