1. A transformer comprising:
- a substrate comprising a semiconductor material;
a first conductor over the substrate, the first conductor defining a generally spiral-shaped signal path having at least one turn;
a second conductor over the substrate, the second conductor defining a generally spiral-shaped signal path having at least one turn, wherein at least a portion of the at least one turn of the first conductor is positioned adjacent to at least a portion of the at least one turn of the second conductor; and
a first magnetic layer between the substrate and the conductors, wherein the at least one turn of the first conductor crosses over the at least one turn of the second conductor.

Abstract
A transformer comprises a substrate comprising a semiconductor material, a first conductor over the substrate, a second conductor over the substrate, and a magnetic layer over the substrate. The first conductor defines a generally spiral-shaped signal path having at least one turn. The second conductor defines a generally spiral-shaped signal path having at least one turn.
