  "textContent": "According to an embodiment, a method for calibrating a local oscillator in an Amplitude Shift Keying (ASK) demodulator of a wireless power transmitter is proposed. The method includes receiving a digital signal corresponding to a voltage or a current of a transmitter coil in a wireless power system implemented with frequency dithering; iteratively adjusting counter values associated with a dithering table of the local oscillator; wherein for each iteration, the method comprises generating in-phase (I) and quadrature (Q) components using the local oscillator, computing a metric based on the I and Q components, and storing the counter values if the computed metric surpasses a previously stored best metric; and configuring the local oscillator with the stored counter values associated with the best metric.",
