Abstract
Aux fins de l'invention, on décrit un dispositif (100) pour la comparaison entre deux tensions d'alimentation (V1, V2), qui comporte deux entrées (1, 2) pour les tensions d'alimentation (V1, V2) et une sortie (8) pour la fourniture d'un signal, ce dispositif livrant de bons résultats indépendamment de l'ampleur des tensions d'alimentation (V1,V2), et à cet effet il est envisagé que le dispositif (100) comporte deux convertisseurs tension/courant (3, 4) accordés et deux miroirs respectivement associés (5, 6), ainsi qu'un comparateur de courant (7) pour les courants réfléchis ( 3,14), et un inverseur (9) à deux sortie numériques (10, 11), disposé à la sortie (8). On décrit aussi un procédé correspondant.
