Patent ID: 7350292

Claim:
A method for affecting an impedance of a portion of an electrical circuit loop in an electrical circuit apparatus comprising: providing an electrical circuit apparatus having at least a portion of an electrical circuit loop including at least one of at least one trace and at least one via, the trace and the via operatively connected together to provide electrical communication therethrough, and dielectric material disposed in operative relationship adjacent at least one of the trace and the via; providing a layer of a magnetic material disposed adjacent at least one of the trace and the via, whereby the layer of magnetic material is disposed in operative relationship near at least one of the trace and the via to affect the impedance of at least one of the trace, the via and the portion of the circuit loop formed by the trace one the via; and providing power to the electrical circuit apparatus, whereby during the providing of power, the layer of magnetic material affects the impedance of the at least one via.
