Abstract

L'INVENTION CONCERNE UN DISPOSITIF POUR COMPENSER LE GAIN D'UN TRANSISTOR, COMPRENANT UNE JONCTION BASE-EMETTEUR, CONTRE DES VARIATIONS DUES A DES CHANGEMENTS DE TEMPERATURE ET QUI COMPREND UNE SOURCE DE POTENTIEL DE FONCTIONNEMENT AYANT DEUX BORNES. SELON L'INVENTION, UN CIRCUIT DE COMPENSATION DE TEMPERATURE EST RELIE EN SERIE, ENTRE LES DEUX BORNES, ET IL COMPREND UN PREMIER MOYEN CONDUCTEUR 376 AYANT UNE CHUTE DE TENSION BASE-EMETTEUR QUI VARIE AVEC LA TEMPERATURE; UN SECOND MOYEN CONDUCTEUR600 AYANT UNE CHUTE DE TENSION QUI EST UN MULTIPLE CONSTANT DE LA CHUTE BASE-EMETTEUR, ET QUI VARIE EN RELATION CONSTANTE AVEC CELLE DU PREMIER MOYEN CONDUCTEUR AVEC LA TEMPERATURE; ET UN TROISIEME MOYEN CONDUCTEUR 610 AYANT UNE IMPEDANCE QUI EST SENSIBLEMENT CONSTANTE AVEC LA TEMPERATURE, LE TRAJET BASE-EMETTEUR DU TRANSISTOR 306 ETANT RELIE ENTRE LA JONCTION DES MOYENS 376 ET 600 ET LA PREMIERE BORNE (MASSE) DE LA SOURCE DE POTENTIEL. L'INVENTION S'APPLIQUE NOTAMMENT AUX AMPLIFICATEURS.
