Abstract

Circuit d'amplification à étage de sortie classe B formé par deux miroirs de courant dont l'un est le complément de l'autre et dont les branches de sortie sont connectées en série entre des bornes d'alimentation. Les branches d'entrée de ces miroirs de courant sont commandées depuis des branches de sortie de troisième et quatrième miroirs de courant, ceux-ci interconnectant les électrodes d'évacuation de chaque groupe de deux transistors qui forment des premier et deuxième amplificateurs de différence à bornes d'entrée communes. Application aux circuits intégrés.
