Embodiments of the invention include an amplifier such as an operational amplifier having an output stage with a reduced quiescent current control transistor device area that provides sufficient quiescent current control for proper operation thereof. The output stage includes a current diverter or diverting arrangement whereby current flowing to the quiescent current control transistor area is reduced by diversion without jeopardizing the proper operation of the operational amplifier. In this manner, the relative size of the quiescent current control transistors can be significantly reduced without sacrificing any of the overall performance of the amplifier.
Les concrétisations de l'invention comprennent un amplificateur tel qu'un amplificateur opérationnel ayant un étage de sortie comportant un transistor de commande de courant de repos de taille réduite, mais suffisamment efficace toutefois pour permettre le bon fonctionnement de l'amplificateur. L'étage de sortie comprend un déviateur de courant qui réduit le courant circulant dans le transistor de commande de courant de repos sans nuire au bon fonctionnement de l'amplificateur opérationnel. De cette façon, la taille du transistor de commande de courant de repos peut être réduite sensiblement sans sacrifier la performance globale de l'amplificateur.
