  • Contactless integrated circuit with high-efficiency electrical power supply circuit
    Patent number: 7580694
    Abstract: A circuit and method for supplying an electronic circuit with a direct supply voltage using high frequency antenna signals. The method includes producing a primary direct voltage equal to a fraction of the supply voltage using at least one antenna signal, producing at least two pumping signals having a frequency lower than the frequency of the antenna signals by means of an oscillator electrically powered by the primary voltage and boosting the primary voltage by means of a charge pump driven by the pumping signals, to obtain the supply voltage.
    Type: Grant
