Abstract: The method involves producing a direct voltage (Vccp) equal to a fraction of a supply voltage (Vcc) from high frequency antenna signals (S1, S2). Pumping signals (H1, H2) having a frequency lesser than the frequency of the antenna signals are produced using a low voltage oscillator (LVOSC) electrically supplied by the voltage (Vccp). The voltage (Vccp) is boosted using a charging pump (PMP2) driven by the signals (H1, H2) for obtaining the supply voltage. Independent claims are also included for the following: (1) an integrated circuit comprising an electronic circuit (2) an electronic circuit comprising a control unit (3) a portable electronic object comprising an integrated circuit.
