Abstract

L'invention est du domaine des amplificateurs électroniques. Elle a pour objet un circuit permettant de limiter la tension de sortie d'un amplificateur pour certaines plages de sa tension d'entrée en provoquant, par une sous-alimentation, un fonctionnement à saturation de l'amplificateur pour les plages considérées de sa tension d'entrée. Elle s'applique par exemple pour éliminer ou niveler les composantes d'un signal dont l'amplitude se situe dans une certaine gamme sans toucher aux autres.
