  "textContent": "A rectifier circuit includes an H-bridge circuit, and rectifies an AC current that flows through a reception antenna. A smoothing capacitor smoothes the output of the rectifier circuit. A demodulator demodulates an FSK-modulated electric power signal. A first comparator compares a voltage Vat a first AC input terminal with a first threshold voltage V, and generates a first detection signal. A second comparator compares a voltage Vat a second AC input terminal with a second threshold voltage V, and generates a second detection signal. A clock generating circuit generates a frequency detection clock CLK_OUT that transits according to a predetermined edge type of the first detection signal and a predetermined edge type of the second detection signal. A frequency detection circuit detects the frequency of the frequency detection clock.",
