摘要：
A data carrier includes at least one coil for the contactless reception of amplitude-modulated signals. A rectifier circuit is connected downstream of the coil. A circuit configuration processes and/or stores data. A supply-voltage control circuit is connected in parallel with the circuit configuration. A current measuring device acts as an amplitude demodulator and is disposed between the coil and the voltage-supply control circuit.
