Abstract
A coil current demodulation method and a circuit based on a wireless charging power transmitter are provided. The method includes the following steps: sampling transmitter coil current signal, carrying out signal processing on the sampled transmitter coil current signal, and completing coil current demodulation. By directly sampling the transmitter coil current signal, one may avoid the problem that the conventional ASK demodulation method has an error in signal sampling.
