Abstract
A wireless power system has a wireless power transmitting device and a wireless power receiving device. The wireless power transmitting device may include ASK decoding circuitry. An inverter controller may supply control signals to an inverter based on a clock signal. To improve wireless transmission at various frequencies of interest, the clock signal used by the inverter controller may be dithered using a modulating signal. To mitigate bit errors in ASK decoding caused by the dithering of the clock signal in the wireless power transmitting device, ASK communication receiving circuitry in the wireless power transmitting device may receive information regarding the modulating signal used to dither the clock signal. The ASK communication receiving circuitry may receive a clock signal that has been dithered using the modulating signal, dither an analog-to-digital converter sampling rate using the modulating signal, or include notch filtering circuitry with parameters determined based on the modulating signal.
