Abstract
A method for forming an integrated transformer is disclosed. The integrated transformer includes a magnetic core situated in a first layer from among multiple layers of a semiconductor layer stack and a first conductor and a second conductor from among multiple conductors. The first conductor is situated within a second layer, above the first layer, from among the multiple layers of the semiconductor layer stack. The second conductor is situated within a third layer, below the first layer, from among the multiple layers of the semiconductor layer stack. The first conductor and the second conductor form a primary winding of the integrated transformer. The integrated transformer additionally includes a secondary winding, wrapped around the magnetic core, situated in the first layer, the second layer, and the third layer.
