Abstract

CIRCUIT D'AMPLIFICATION SYMETRIQUE FORME PAR DEUX TRANSISTORS DONT LES EMETTEURS SONT A LA MASSE A TRAVERS DEUX RESISTANCES AYANT LA MEME VALEUR OHMIQUE. LE SIGNAL D'ENTREE EST FOURNI ENTRE LES BASES DES TRANSISTORS, LE SIGNAL DE SORTIE ETANT PRELEVE SUR LEURS COLLECTEURS. ON A CONSTATE QU'UN TEL CIRCUIT D'AMPLIFICATION OFFRE UNE MEILLEURE LINEARITE JUSQU'A UNE TENSION D'ENTREE DE 200 MV LORSQUE LA VALEUR OHMIQUE R DES RESISTANCES D'EMETTEUR RESPECTE LA RELATION R 0,56 UI DANS LAQUELLE U EST LA TENSION DE TEMPERATURE TANDIS QUE I INDIQUE LE COURANT DE REPOS DE COLLECTEUR (EN L'ABSENCE DE SIGNAL D'ENTREE ENTRE LES BASES DES TRANSISTORS). CETTE VALEUR OHMIQUE R EST TRES FAIBLE (ET N'ATTEINT QUE 14 OHMS EN PRESENCE D'UN COURANT DE REPOS DE COLLECTEUR A INTENSITE DE 1MA), DE SORTE QUE LA PENTE DE FLANC N'EST DIMINUEE QUE DANS UNE FAIBLE MESURE PAR LES RESISTANCES D'EMETTEUR, CE QUI A COMME CONSEQUENCE QUE LA SENSIBILITE DU CIRCUIT DIMINUE A PEINE. APPLICATION AUX AMPLIFICATEURS DE SIGNAUX A AUDIOFREQUENCES.
