Claim 10:
11. An integrated circuit for a wireless power transmitter, the wireless power transmitter configured for transmitting alternating current (AC) wireless signals to a wireless power receiving system, the AC wireless signals including, at least, wireless power signals and amplitude shift keying (ASK) wireless data signals, the integrated circuit comprising:
an amplifier, the amplifier including:, at least one transistor that is configured to receive a driving signal at a gate of the at least one transistor and invert a direct current (DC) input power signal to generate the AC wireless signals at an operating frequency, and
a damping circuit that is configured to dampen the AC wireless signals during transmission of the ASK wireless data signals, wherein the damping circuit includes at least a damping transistor that is configured to receive, from a transmitter controller, a damping signal for switching the damping transistor to control damping during transmission of the ASK wireless data signals; and
a filter circuit including, at least, a filter capacitor and a filter inductor, the filter circuit configured for optimization based on a filter quality factor.
