Abstract: A charging circuitry for receiving power through wireless power transfer comprises: a power receiver configured to receive an alternating current (AC) wireless power signal and store energy through resonance; a rectifying switch configured to selectively connect an output of the power receiver to a load a comparator connected to the output of the power receiver and configured to identify an extreme point of an output voltage signal (vs) of the power receiver and configured to cause the rectifying switch to be turned on based on identification of the extreme point; and a delay circuit configured to control a state of the comparator such that the comparator is disabled for a delay period between successive instances of the rectifying switch being turned on.
