Abstract:
1. An integrated circuit transformer, comprising: a semiconductor substrate for supporting a plurality of layers of an integrated circuit; a plurality of substantially octagon shaped outer low primary windings configured in a 2D grid pattern wherein each outer low primary winding is adjacent to two other outer low primary windings; a plurality of substantially octagon shaped inner high primary windings configured in a 2D grid pattern wherein each inner high primary winding is routed within its respective outer low primary winding; and a substantially octagon shaped secondary winding routed between each outer low primary winding and inner high primary winding and electrically coupled in the center of said grid, said routing adapted to maximize power coupling and impedance transformation from said high and low primary windings to said secondary winding.
