METHOD AND DEVICE FOR CONTROLLING THE OPERATION OF A PORTABLE ELECTRONIC OBJECT SUPPLIED WITH POWER VIA AN ANTENNA

摘要

A device including an antenna to which is connected a rectifier (RD) delivering a primary DC supply voltage (VNR) at its output (BS), and stabilising means (1, ST) for generating a stabilised DC voltage (VDD) from said primary voltage. First means (R3, R4, R5) generate a first predetermined voltage threshold corresponding to a predetermined stabilised DC supply voltage level. A comparator means (CP) has an output (BS2) connected to a processing means of which a first input is connected to the output of the first generating means while the second input is connected to the rectifier output (BS). Furthermore, a load (RBL) having a selected impedance is connected between said rectifier output and the ground via a controllable switching means (T200) having a control input connected to the output of the comparator means (CP).
