Abstract

L'INVENTION CONCERNE UN CONVERTISSEUR ANALOGIQUE-NUMERIQUE EFFECTUANT UNE CONVERSION A N ELEMENTS BINAIRES EN N ITERATIONS. LES DEUX CONDENSATEURS C2 ET C2 PERMETTENT DE CALCULER A CHAQUE ITERATION LA TENSION DE REFERENCE VRIVR2. LES DEUX CONDENSATEURS ET L'AMPLIFICATEUR AMP PERMETTENT SOIT DE CALCULER LA TENSION VI1VI-VRI SI LE IELEMENT BINAIRE EST A 1, SOIT DE CONSERVER LA TENSION VI1VI. A CHAQUE ITERATION, VI EST COMPARE A VRI. L'INVENTION S'APPLIQUE A DES CONVERTISSEURS INTEGRES RAPIDES.
