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.
