AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
Claims 17-20 were previously disclaimed.
Claims 1-16 are cancelled.
1. A multiple inductor array comprising:
a first node that receives a first current and a second current;
a first inductor coil, coupled to the first node and to a second node, that communicates the first current in a clockwise direction and generates a first magnetic field;
a second inductor coil, coupled to the first node and to a third node, that communicates the second current in a counter clockwise direction and generates a second magnetic field having an opposing orientation to the first magnetic field; and
wherein the first magnetic field and the second magnetic field at least partially cancel at an interference point.
