1. A circuit comprising:
- a first portion to sense a signal within a frequency range; and
a second portion to generate a signal having a current component at substantially a same frequency and substantially 180 degrees out of phase from the sensed signal; and
a combining circuit to provide a total switching signal to power a device by combining a switching signal corresponding with the sensed signal and the signal having the current component.

Abstract
A system is provided that includes a power distribution network to provide a switching current and a resonance reduction circuit to sense the switching current within a frequency range and to generate a resonance reduction signal having a current component at substantially a same frequency and substantially 180 degrees out of phase from the sensed switching current. The power distribution network may combine the switching current with the resonance reduction signal to provide a total switching current that may be provided to a processor as the powering signal.
