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

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.
