Patent ID: 7474190

Claim:
A component arrangement, comprising: a semiconductor body including a face; a planar transformer including a primary winding, a first planar winding section, and a second planar winding section, each vertically spaced apart from each other, the first planar winding section forming at least a part of the secondary winding and having a first connection forming a first connection of the secondary winding; a dielectric layer positioned on the face and isolating the primary winding from the first planar winding section, and wherein the second planar winding section is disposed between the first planar winding section and the primary winding; wherein the first planar winding section has more than one turn, the second planar winding section having exactly one turn, a first end, and a second end, the first and second ends separated by a gap; and dimensions of the second planar winding section in a lateral direction corresponding at least approximately to the dimensions of at least one of the first planar winding section and the primary winding.
