Abstract: |
|||
| The invention relates to a data medium comprising at least one inductor (1) for contactless reception of amplitude-modulated signals. The data medium also comprises a rectifier circuit (2) connected in series to the inductor (1), and a circuit (3) for processing and/or storing data. A supply voltage regulating circuit (4) is connected in parallel to the circuit (3). A current measuring device (SME; RM, DS; SP, DS; TR, DS; D11, D22, DS; SP1, SP2, DS) which functions as an amplitude demodulator is arranged between the inductor (1) and the supply voltage regulating circuit (4). | |||
