Abstract
Multiple inductor structures and methods for providing low mutual inductance between the inductors are described. In various embodiments of the invention, the polarities of the inductors are positioned such that parasitic mutual inductance is reduced by causing electro-magnetic fields to at least partially cancel resulting in a reduction in interference between the inductors. The polarities of the magnetic fields produced by each inductor are opposite to each other so that at least a partial cancellation results when the fields interfere with each other.
