Abstract
In an embodiment, a method for transmitting data from a wireless power receiver to a wireless power transmitter includes: wirelessly receiving power at a first frequency from a transmitter LC tank using a receiver LC tank; rectifying a voltage of the receiver LC tank using a rectifier; and while wirelessly receiving power, controlling a transistor coupled to the receiver LC tank to cause inflections in a transmitter current flowing through the transmitter LC tank to transmit data, detecting time locations of the inflections of the transmitter current within an oscillating cycle of the transmitter current based on a magnitude of the transmitter current, and determining the data based on the detected time locations.
