Abstract
Systems and methods for phase demodulation is described. A wireless power transmitter can include a controller, a transmission coil, and an integrated circuit connected to the controller and the transmission coil. The integrated circuit can be configured to measure a voltage of a transmission coil of a wireless power transmitter. The integrated circuit can be further configured to generate, based on the measured voltage, a pulse signal comprising a plurality of pulses. The integrated circuit can be further configured to send the pulse signal to the controller of the wireless power transmitter. The controller can be configured to perform phase demodulation using the pulse signal.
