Claim 16:
17. A listener for a Near-Field Communications Direct Charge (NFC-DC) system comprising:
a transmitter antenna configured to couple with at least one other antenna and transmit alternating current (AC) wireless signals to the at least one other antenna, the AC wireless signals including wireless power signals and wireless data signals;
an integrated circuit including
a transmitter controller that is configured to (i) provide a driving signal for driving the transmitter antenna based on an operating frequency for the NFC-DC system and (ii) perform one or more of encoding the wireless data signals, decoding the wireless data signals, receiving the wireless data signals, or transmitting the wireless data signals, and
a damping circuit configured for damping the AC wireless signals during transmission of the wireless data signals, the damping circuit including, at least, a damping transistor configured for receiving a damping signal from the transmitter controller, the damping signal configured for switching the damping transistor to control damping during transmission of the wireless data signals; and

an amplifier, the amplifier including at least one transistor that is configured to receive the 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 the operating frequency.
