Abstract

AMPLIFICATEUR DE SORTIE INTEGRE COMPORTANT UN PREMIER TRANSISTOR DE SORTIE T DONT L'EMETTEUR EST RACCORDE A UNE SORTIE 1, UN DEUXIEME TRANSISTOR DE SORTIE T AINSI QU'UNE SOURCE DE COURANT DE REPOS 3 RACCORDEE A LA BASE DU PREMIER TRANSISTOR DE SORTIE. POUR LIMITER AU MINIMUM LES DISTORSIONS HAUTE FREQUENCE PAR LE CHOIX D'UNE VALEUR MINIMALE DE L'INTENSITE DU COURANT SUR LEQUEL EST REGLEE LADITE SOURCE DE COURANT DE REPOS, ON A ELIMINE L'INFLUENCE DU COEFFICIENT D'AMPLIFICATION DE COURANT DUDIT PREMIER TRANSISTOR, COEFFICIENT QUI EST FORTEMENT SUJET A DES FLUCTUATIONS; CETTE ELIMINATION RESULTE DU FAIT QUE LA JONCTION BASE-EMETTEUR DU PREMIER TRANSISTOR DE SORTIE EST SHUNTEE PAR UNE JONCTION SEMI-CONDUCTRICE D. APPLICATION: RADIORECEPTEURS.
