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.
Claims5
A transformer comprising:
- a substrate comprising a semiconductor material;
- a first conductor over the substrate, the 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;
- a voltage tap conductively coupled to the conductor at a node between end nodes of the conductor;
- and
- a first magnetic layer between the substrate and the first conductor, and a second magnetic layer between the first conductor and the second conductor, wherein the first magnetic layer is coupled to the second magnetic layer.
