    • The portable object is equipped with an antenna inductively coupled to a fixed station of a remote transmission device. The portable object comprises a variable load impedance and a rectifier connected in parallel to the terminals of the antenna, a regulation loop of the voltage at the terminals of the load impedance, connected between the output of the rectifier and a control terminal of the load impedance. The regulation loop comprises, in series, means for determining a difference between a setpoint voltage and the output voltage of the rectifier, a one-bit analog-to-digital converter, and command means of integrator type. The command means comprise a gain control input connected to an output of the gain control means receiving on input signals representative of the difference. Demodulation means are connected to the output of the converter.
    • 便携式物体配备有电感耦合到远程传输设备的固定站的天线。 便携式物体包括可变负载阻抗和与天线的端子并联连接的整流器,连接在整流器的输出端和负载阻抗的控制端之间的负载阻抗端子处的电压的调节回路 。 调节回路包括串联的装置,用于确定整流器的设定点电压和输出电压之间的差值,一位模数转换器和积分器类型的指令装置。 命令装置包括连接到增益控制装置的输出的增益控制输入,用于接收表示差的输入信号。 解调装置连接到转换器的输出端。
