Abstract
In a data carrier (1), or a circuit (3) for such a data carrier (1), in which data processing means (20) are included which can be supplied with a supply voltage (V) and in which, during the processing of data while utilizing a characteristic value, a current peak pattern which is significant of the characteristic value occurs on its supply voltage drain terminals (27, 29, 31, 33 and 28, 30, 32 and 34), current peak pattern suppression means are associated with the data processing means (20;) these suppression means are preferably formed by filter means (36) which include a capacitor (37) which is arranged in the direct vicinity of the data processing means (20) and is connected to the data processing means (20) via low-ohmic connection segments (40, 41, 42, 43, 44, 45, 46, 47).
