Abstract
A receiver for wireless power transfer includes a plurality of passive elements including a coupling element configured to capture an incoming spread spectrum signal, an active switch coupled to the plurality of passive elements, and a controller to generate a control signal for the active switch. The control signal changes a state of the active switch to vary a resonance condition established by the plurality of passive elements.
