Claim Text:
1. A method for fabricating an apparatus, comprising: winding a first strip of conductive material on a first layer of a multi-layer substrate of the apparatus according to a first number of turns to form a first inductor; winding a second strip of conductive material on the first layer of the multi-layer substrate and, in part, on a second layer of the multi-layer substrate according to a second number of turns to form a second inductor, wherein the first strip of conductive material and the second strip of conductive material are wound to form a spiraled structure such that the second strip of conductive material is magnetically coupled with the first strip of conductive material; forming a third strip of conductive material around the first inductor and the second inductor on a third layer of the multi-layer substrate as viewed from a perspective perpendicular to the third layer, wherein a first part of the third strip of conductive material is shorted to a second part of the third strip of conductive material via a fourth strip of conductive material, wherein the first inductor and the second inductor overlap the fourth strip of conductive material as viewed from a perspective perpendicular to the third layer, and wherein the third strip of conductive material is used to provide a reference potential for a circuit comprising the first inductor and the second inductor; and setting ports for the spiraled structure.
