Abstract

L'INVENTION CONCERNE UN AMPLIFICATEUR A GAIN REGLE QUI COMPREND UN TRANSISTOR AVEC UNE BASE, UN EMETTEUR ETUN COLLECTEUR, UNE SOURCE DE SIGNAUX D'ENTREE ETANT RELIEE A LA BASE ET UNE IMPEDANCE DE CHARGE AU COLLECTEUR. SELON L'INVENTION, UNE DIODE PIN 112 EST RELIEE ENTRE L'EMETTEUR ET UN POINT DE POTENTIEL DE REFERENCE (MASSE), ET UNE SOURCE DE TENSION DE REGLAGE DU GAIN 140 EST RELIEE AU TRANSISTOR 110 POUR POLARISER DE FACON VARIABLE LE TRANSISTOR 110 ET LA DIODE PIN 112. L'INVENTION S'APPLIQUE NOTAMMENT AUX AMPLIFICATEURS POUR TELEVISEURS.
