Abstract

L'INVENTION CONCERNE UN AMPLIFICATEUR LINEAIRE DIFFERENTIEL. IL EST CARACTERISE PAR LE FAIT QUE LE COLLECTEUR DE CHAQUE TRANSISTOR AYANT COMME BASE L'UNE DES ELECTRODES D'ENTREE PREND, PAR RAPPORT AU POLE D'ALIMENTATION UN POTENTIEL DE REPOS INFERIEUR A LA DIFFERENCE ENTRE LES TENSIONS COLLECTEUR-EMETTEUR ET BASE-EMETTEUR EN SATURATION, AFFECTEE A SON COURANT D'EMETTEUR, AU MOYEN D'UNE RESISTANCE DE COLLECTEUR, MONTEE ENTRE CE COLLECTEUR ET LE PREMIER POLE. L'INVENTION S'APPLIQUE EN ELECTRONIQUE.
