Abstract: A method and system for operating a power circuit capable of transmitting and receiving wireless power. The method includes determining that the power circuit is operating in receive mode, and, based thereon, having a first equivalent capacitance. The method further includes determining that the power circuit is operating in the transmit mode, and, based thereon, having a second equivalent capacitance. The first equivalent capacitance being different than the second equivalent capacitance.

Abstract: A method for modulating a signal including operating a circuit in a first arrangement during a first operating interval and switching the circuit between the first arrangement and a second arrangement during a first modulation interval to vary a load on the circuit to produce a first amplitude shift keying (ASK) signal. The method further includes detecting a voltage on the circuit crossing a threshold level and operating the circuit in the second arrangement during a second operating interval. The method also includes switching the circuit between the second arrangement and the first arrangement during a second modulation interval to vary the load on the circuit to produce a second ASK signal.

Abstract: A system and method for improving ASK packet transfer reliability and power dissipation efficiency at light-load or no-load conditions of a receiving device is provided. In an embodiment, the receiving device includes a dissipating element coupled to a rectifier. The dissipating element is connected to a reference voltage at a first duration corresponding to a transmission of the ASK packet. The dissipating element is disconnected from the reference voltage a second duration corresponding to an end of the transmission of the ASK packet.
