Title (EN) WIDE DYNAMIC RANGE AMPLIFIER GAIN CONTROL
(FR) COMMANDE DE GAIN D'AMPLIFICATEUR A LARGE GAMME DYNAMIQUE
Abstract: front page image
(EN)Linear wide dynamic range variable gain amplifiers can be configured using a variable gain amplifier having an abbreviated gain control range in combination with a discrete attenuator controlled to select an attenuation from a predetermined set of attenuation values. The variable gain amplifier is configured to provide substantially linear gain control over the abbreviated gain control range, where the abbreviated gain control range is less than a total desired gain control range. The difference between adjacent attenuation values in the set of attenuation values is configured to be approximately less than or equal to the abbreviated gain control range.
(FR)Selon cette invention, des amplificateurs de gain variable linéaires à large gamme dynamique peuvent être conçus au moyen d'un amplificateur de gain variable possédant une gamme de commande de gain abrégé combinée à un atténuateur discret commandé pour sélectionner une atténuation d'un ensemble prédéterminé de valeurs d'atténuation. Cet amplificateur de gain variable est conçu pour obtenir une commande de gain sensiblement linéaire dans la gamme de commande de gain abrégé, cette gamme de commande de gain abrégé étant inférieure à une gamme de commande de gain voulue totale. La différence entre des valeurs d'atténuation adjacentes dans l'ensemble de valeurs d'atténuation est conçue pour être approximativement inférieure ou égale à la gamme de commande de gain abrégé.
