An apparatus and method for reducing stray magnetic fields include a decoupling circuit includes a balun that comprises a transmission line. The transmission line includes a first spiral positioned substantially parallel to a first plane, the first spiral emanating from a inner portion of the first spiral in a first spiral direction. The transmission line also includes a second spiral positioned substantially parallel to the first plane, the second spiral emanating from a inner portion of the second spiral in the first spiral direction, wherein the inner portion of the first spiral is electrically coupled to the inner portion of the second spiral, and wherein the transmission line comprises a signal line and a ground line. The balun further comprises a first capacitor electrically coupled to the transmission line.
