1. A method comprising:
- forming a first conductor over a substrate comprising a semiconductor material, wherein the forming the first conductor comprises forming the first conductor such that the first conductor defines a generally spiral-shaped signal path having at least one turn;
forming a second conductor over the substrate such that the second conductor defines a generally spiral-shaped signal path having at least one turn, wherein the forming the first conductor and the forming the second conductor comprise forming the first and second conductors such that the first conductors are positioned side-by-side;
forming a first magnetic layer over the substrate; and
forming a second magnetic layer over the first conductor and the second conductor,wherein the forming the first magnetic layer and the forming the second magnetic layer comprise forming the first and second magnetic layers connected to each other.

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.
