Claim:
1. A two-walled coupled inductor comprising: a first electrically conductive wall having a first end, a second end and a first width; a second electrically conductive wall separated from the first wall by a slit, the second wall having a first end, a second end and a second width; a first node where the first ends of the first and second electrically conductive walls are coupled; a second node where the second ends of the first and second electrically conductive walls are coupled; and an electrically conductive stub coupled to one of the first electrically conductive wall and the second electrically conductive wall and configured to be coupled to a power supply; wherein an inductance of a common mode is based at least in part on a length of the electrically conductive stub; and wherein an inductance of a differential mode is based at least in part on a width of the first wall and a width of the second wall.
