| Abstract | A circuit for obscuring gate switching noise includes a synchronous clock source; an asynchronous clock source; at least one current source; and a random number generating circuit for receiving clock inputs from the synchronous clock source and the asynchronous clock source, the random number generating circuit generating randomly changing asynchronous digital control signals for controlling the current source.
L'invention porte sur un circuit destiné à obscurcir du bruit de commutation de porte qui comprend une source d'horloge synchrone ; une source d'horloge asynchrone ; au moins une source de courant ; et un circuit générateur de nombre aléatoire pour recevoir des entrées d'horloge en provenance de la source d'horloge synchrone et de la source d'horloge asynchrone, le circuit générateur de nombre aléatoire générant des signaux de commande numérique asynchrones variant aléatoirement pour commander la source de courant. |
