  • Inductive coupling reader comprising means for extracting a power supply voltage
    Patent number: 7665664
    Abstract: The present invention relates to a method for supplying a power supply voltage (Vccr) to a contactless integrated circuit reader (RD1) that is in a passive operating mode, in the presence of an external alternating magnetic field (FLD2), the reader comprising an antenna circuit (ACT) substantially tuned to a working frequency (F0). According to the present invention, the method comprises the steps of taking off in the antenna circuit (ACT) an alternating voltage (Vcd) induced in the antenna circuit by the external magnetic field (FLD2), and rectifying the induced voltage to supply an auxiliary supply voltage (Vccr).
