An apparatus includes a first conductive loop coupled to conduct a first current and a second conductive loop coupled in parallel with the first conductive loop and further coupled to conduct a second current. A first conductive portion forms a part of the first conductive loop and the second conductive loop. The first conductive portion is coupled to conduct the first current and the second current. In at least one embodiment of the apparatus, the first conductive loop and the second conductive loop are planar inductors formed in a conductive layer on a substrate of an integrated circuit.
