DISPOSITIF A CIRCUIT INTEGRE SECURISE PAR ATTENUATION DES SIGNATURES ELECTRIQUES

摘要

The invention concerns an integrated circuit device (2) designed to be incorporated in a portable object with memory, in particular of card format. The invention is characterised in that the integrated circuit device (2) comprises at least a capacitor (8) for attenuating the amplitude of current peaks (Idd) consumed by the device integrated circuit (2). The invention is particularly useful for attenuating electric signatures in smart cards.
