Abstract: An electromagnetic transponder including an oscillating circuit adapted to extracting from a radiating field a high-frequency amplitude-modulated signal, circuitry for extracting from said high-frequency signal an approximately D.C. supply voltage, a demodulator of data carried by the high-frequency signal, and circuitry for separately regulating the supply voltage and a useful voltage carrying the data.
