Abstract
An inductive wireless power enabled device may comprise a transceiver including a plurality of switches coupled with a resonant tank, and control logic configured to drive the plurality of switches to operate the resonant tank in one of a transmit mode and a receive mode. Another inductive wireless power enabled device may comprises a transceiver including a plurality of switches coupled with a resonant tank. The transceiver may be configured to both transmit a wireless power signal through the resonant tank and generate power from an incoming wireless power signal through the resonant tank depending on a current operational mode. A related method for operating a wireless power enabled device according to either a transmit mode or a receive mode is also disclosed.
