1. An apparatus comprising:
a rectifier coupled to a receiver coil, the receiver coil configured to be magnetically coupled to a transmitter coil of a wireless power transfer system, wherein the rectifier is configured to convert an alternating current voltage into a direct current voltage;
a first communication apparatus configured to provide a low speed communication to a transmitter of the wireless power transfer system, wherein the first communication apparatus comprises an amplitude shift keying (ASK) modulator configured to provide the low speed communication between the apparatus and the transmitter of the wireless power transfer system;
a second communication apparatus configured to provide a high-speed communication to the transmitter of the wireless power transfer system, wherein the high-speed communication provided by the second communication apparatus is enabled through the low speed communication provided by the first communication apparatus;
a control unit comprising a processor; and
a power converter connected to an output of the rectifier, and wherein:
the control unit is fabricated in a first semiconductor die; and
the rectifier, the ASK modulator and the power converter are fabricated in a second semiconductor die.
