Abstract

CONVERTISSEUR DE COMPENSATION NUMERIQUE DES ERREURS INITIALES DE GAIN ET D'ECARTS DE STATISME ET DES ERREURS DUES AUX EXCURSIONS DE GAIN ET ECARTS DE STATISME PAR SUITE DE VARIATIONS DE TEMPERATURE. UN SIGNAL ANALOGIQUE D'ENTREE (VIN) EST ENVOYE A UN PREMIER CONVERTISSEUR ANALOGIQUE-NUMERIQUE 4 DONT LE SIGNAL DE SORTIE EST D'UNE PART ENREGISTRE DANS UN MICROPROCESSEUR 16 ET APPLIQUE A UN CONVERTISSEUR LINEAIRE NUMERIQUE-ANALOGIQUE 6. LE SIGNAL DE SORTIE DE CE CONVERTISSEUR LINEAIRE EST ADDITIONNE A LA TENSION ANALOGIQUE INITIALE D'ENTREE ET LA DIFFERENCE EST APPLIQUEE A L'APPAREIL DE CONVERSION SOUS FORME D'UN SIGNAL D'ENTREE INCONNU. CE PROCESSUS SE POURSUIT JUSQU'A OBTENTION DE LA RESOLUTION VOULUE. LE SIGNAL DE SORTIE D'UN CAPTEUR DE DIFFERENCE DE TEMPERATURE 14 EST TRAITE DE LA MEME MANIERE. APPLICATION A LA COMPENSATION DES DERIVES DUES AUX VARIATIONS DE TEMPERATURE.
