<p>In a data carrier (1) that is arranged to receive a signal (S) in a non-contacting manner there is provided a circuit (2) that is arranged, by using the signal (S), to generate a supply voltage (V) for parts of the circuit (2), the circuit (2) has a storage stage (5) that is arranged to store information capacitively, the information being represented by a value of an information voltage (UI) arising at the storage stage (5), which value of the information voltage (UI) is at most equal to the value of the supply voltage (V), and the circuit (2) has an evaluation stage (14) to which the information voltage can be fed and that are arranged to evaluate the information voltage (UI), with the help of a comparison voltage (UC), for the information represented by the information voltage (UI), the comparison-voltage generating stage (15) that is arranged to generate and emit the comparison voltage (UC) being implemented separately from the evaluation stage (14), and the evaluation stage (14) being arranged to receive the comparison voltage (UC).</p> |
