  "textContent": "In an embodiment, a wireless power transmitter of a wireless charging system may detect an amplitude shift keying (ASK) carrier signal sent by a wireless power receiver of the wireless charging system, attenuate the ASK carrier signal, and clamp the attenuated ASK carrier signal to a predetermined signal strength range. The wireless power transmitter may detect peak values of the clamped signal, and generate a zero-crossing signal representing zero-crossing points of the clamped signal. The wireless power transmitter may sample the peak values of the clamped signal at timing instants determined by the zero-crossing signal to produce a demodulated ASK envelope signal of the ASK carrier signal.",
