Title (EN) A METHOD AND APPARATUS FOR DETECTING ON-DIE VOLTAGE VARIATIONS
(FR) PROCEDE ET APPAREIL PERMETTANT DE DETECTER DES VARIATIONS DE TENSION A L'INTERIEUR D'UNE PUCE
Abstract:
(EN) On-die voltage and/or frequency detectors. For one aspect, an adaptive frequency clock generation circuit includes a droop detector to detect a supply voltage level and to cause the frequency of an on-die clock signal to be adjusted accordingly.
(FR) La présente invention concerne des détecteurs de la tension et/ou de la fréquence à l'intérieur d'une puce. Dans un aspect, l'invention concerne un circuit générateur d'horloge à fréquence adaptative comprenant un détecteur de fléchissement qui détecte un niveau de tension d'alimentation et qui entraîne un ajustement approprié de la fréquence d'un signal d'horloge à l'intérieur de la puce.
