Abstract
Various embodiments relate to digital demodulation for wireless power transmission. A wireless power transmitter includes a transmitter coil and a controller. The transmitter coil is configured to wirelessly couple to a receiver coil of a wireless power receiver to transfer power to the wireless power receiver responsive to a coil current applied to the transmitter coil. The wireless power receiver is configured to modulate at least one electrical condition of the wireless power receiver to modulate the coil current at the transmitter coil. The controller is configured to sample one or more electrical signals of the wireless power transmitter, and digitally demodulate the sampled one or more electrical signals to obtain a communication received from the wireless receiver responsive to the modulation of the at least one electrical condition of the wireless power receiver.
