摘要： Techniques for calibrating a crystal oscillator of a wireless device are provided. A method according to these techniques includes operating a transmit path of the wireless device at a first carrier frequency, configuring a receive path of the wireless device to receive at a second carrier frequency, the second carrier frequency being offset from the first carrier frequency by a first frequency offset, transmitting a tone using the transmit path at a frequency that is offset from the first carrier frequency by a second frequency offset that is different than the first frequency offset, receiving a second tone via the receive path, and determining the oscillator error based on the second tone.

摘要： A wireless power transmitting apparatus transmits an electric power signal comprising any one from among an electric field, a magnetic field, and an electromagnetic field to a wireless power receiving apparatus. A reflector coil is arranged at a distance from a radiation coil. A driving power supply supplies a driving current to the radiation coil. A first phase control circuit controls the phase of the current that flows through the reflector coil so as to stabilize, to a predetermined value, the phase difference between the current that flows through the reflector coil and the current that flows through the radiation coil.
