1. A wireless power transfer system operatively associated with a wearable electronic device and a wireless charging apparatus, the wireless power transfer system comprising:
a wireless power receiver system operatively associated with the wearable electronic device, the wireless power receiver system comprising:
a receiver antenna configured for (i) coupling with a transmitter antenna operatively associated with the wireless charging apparatus and (ii) receiving alternating current (AC) wireless signals from the transmitter antenna; and
a receiver controller configured to perform one or more of encoding wireless data signals, decoding the wireless data signals, receiving the wireless data signals, or transmitting the wireless data signals; and
a wireless power transmission system operatively associated with the wireless charging apparatus for the wearable electronic device, the wireless power transmission system comprising:
the transmitter antenna configured to (i) couple with the receiver antenna of the wireless power receiver system and (ii) transmit the AC wireless signals to the receiver antenna, the AC wireless signals including wireless power signals and wireless data signals;
a transmission integrated circuit including:
a transmitter controller that is configured to (i) provide a driving signal for driving the transmitter antenna 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 that is configured to dampen the AC wireless signals to facilitate transmission of the wireless data signals, wherein the damping circuit includes at least a damping transistor that is configured to receive, from the transmitter controller, a damping signal for switching the damping transistor to control damping to facilitate transmission of the wireless data signals; and
an 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 power (DC) input power signal to generate the AC wireless signals.
