Abstract

L'INVENTION CONCERNE UN CIRCUIT AMPLIFICATEUR ELECTRIQUE POUR SIGNAUX DE POLARITE QUELCONQUE. ELLE SE RAPPORTE A UN CIRCUIT AYANT UN PREMIER ET UN SECOND AMPLIFICATEUR DIFFERENTIEL OP1, OP2, LE PREMIER TRANSMETTANT A UNE CHARGE L UN COURANT DONT LA VALEUR VARIE AVEC LE SIGNAL D'ENTREE TRANSMIS AUX BORNES A, B, MAIS QUI EST INDEPENDANT DE LA VALEUR DE LA CHARGE. LE SECOND AMPLIFICATEUR OP2 MAINTIENT LE RAPPORT DES POTENTIELS DE SORTIE DE L'AMPLIFICATEUR RAPPORTES A UN POTENTIEL DE REFERENCE A UNE VALEUR TELLE QUE L'EXCURSION DE POTENTIEL DISPONIBLE A LA SORTIE DU CIRCUIT, POUR UNE TENSION DONNEE D'ALIMENTATION, PEUT ETRE MAXIMALE. APPLICATION AUX APPAREILS DE MESURE DES QUANTITES BIDIRECTIONNELLES, PAR EXEMPLE DES ENERGIES.
