FREQUENCY SHIFT KEYING DEMODULATION FOR WIRELESS POWER AND RELATED SYSTEMS, METHODS, AND DEVICES

Frequency shift keying (FSK) demodulation for wireless power and related systems, methods, and devices is disclosed. An apparatus for a wireless power receiver includes a timing circuit and a processing core separate from the timing circuit. The timing circuit is to obtain a timer count every predetermined number of like edges of a frequency shift keying (FSK) wireless power signal. The FSK wireless power signal is to communicate data bits. The processing core is to determine the data bits of the FSK wireless power signal responsive to the obtained timer counts.
