Abstract

CIRCUIT MULTIPLICATEUR ELECTRONIQUE A DECOUPEUR. SELON UNE FORME DE REALISATION IL COMPREND UN MULTIPLICATEUR A TRANSCONDUCTANCE VARIABLE DU TYPE A DEUX PAIRES DE TRANSISTORS A EMETTEURS COUPLES, LES COLLECTEURS DE L'UNE DES PAIRES ETANT RELIES EN CROIX AUX COLLECTEURS DE L'AUTRE PAIRE. POUR PERMETTRE A LA POLARITE EFFECTIVE DE L'UN DES SIGNAUX D'ENTREE ARRIVANT SUR LE MULTIPLICATEUR D'ETRE INVERSEE DE TEMPS EN TEMPS A DES FINS DE CORRECTIONS DE LA DERIVE, CE SIGNAL D'ENTREE EST APPLIQUE A UN CIRCUIT DE COMMUTATION A SEMI-CONDUCTEURS QUI L'APPLIQUE ALTERNATIVEMENT SUR LES BASES RESPECTIVES D'UNE AUTRE PAIRE DE TRANSISTORS A EMETTEURS COUPLES. LES COLLECTEURS DES TRANSISTORS DE CETTE AUTRE PAIRE SONT BRANCHES EN SERIE SUR LES EMETTEURS COUPLES DES TRANSISTORS RESPECTIFS DES PAIRES A EMETTEURS COUPLES DANS LE MULTIPLICATEUR A TRANSCONDUCTANCE VARIABLE. APPLICATION AUX COMPTEURS DE KILOWATTHEURES ELECTRONIQUES.
