Abstract

CET AMPLIFICATEUR EQUILIBRE EST MUNI D'UN PREMIER ET D'UN DEUXIEME TRANSISTOR DE MEME TYPE DE CONDUCTION; LES TRAJETS COLLECTEUR-EMETTEUR DE CES TRANSISTORS SONT BRANCHES EN SERIE ENTRE DEUX BORNES D'ALIMENTATION. L'EMETTEUR DU PREMIER TRANSISTOR EST RACCORDE AU COLLECTEUR DU DEUXIEME TRANSISTOR AINSI QU'A UNE BORNE DE SORTIE, ALORS QUE LA BASE DU PREMIER TRANSISTOR EST RACCORDEE A UNE BORNE D'ENTREE. LES PROPRIETES DE CET AMPLIFICATEUR DEVIENNENT INTERESSANTES EN CE QUI CONCERNE SA LINEARITE, SON INFLUENCE AUX FLUCTUATIONS DE TEMPERATURE ET SA LARGEUR DE BANDE SI, A L'AIDE D'UN MONTAGE EN SERIE COMPORTANT UNE JONCTION SEMICONDUCTRICE ET UNE RESISTANCE, LA TENSION BASE-EMETTEUR DU PREMIER TRANSISTOR EST MESUREE PUIS APPLIQUEE EN OPPOSITION DE PHASE A TRAVERS UN CIRCUIT DE COUPLAGE A LA JONCTION BASE-EMETTEUR DU DEUXIEME TRANSISTOR. APPLICATION : RECEPTEUR DE TELEVISION.
