NON-CONTACT POWER SUPPLY SYSTEM, RECEIVING APPARATUS, AND ANALOG CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power supply system, a receiving apparatus, and an analog circuit that can achieve FSK communication in a low power consumption and space saving manner.SOLUTION: A non-contact power supply system 100 supplies electric power from a transmitting apparatus (TX) 200 to a receiving apparatus (RX) 300 by a non-contact power supply method. The transmitting apparatus (TX) 200 comprises: a transmission coil 202; a driver 204 for having transmission coil 202 generate a power signal in a form of electromagnetic field; and an FSK modulation unit 240 for transmitting an FSK signal via the transmission coil 202. The receiving apparatus (RX) 300 comprises: a reception coil 302; an FSK demodulation unit 330 for demodulating the FSK signal received via the reception coil 302; and a controller 312 into which the FSK signal demodulated by the FSK demodulation unit 330 is input. The FSK demodulation unit 330 is composed of an analog circuit.
