Title (EN) DC-COMPENSATION LOOP FOR VARIABLE GAIN AMPLIFIER
(FR) BOUCLE DE COMPENSATION DE COURANT CONTINU POUR AMPLIFICATEUR A GAIN VARIABLE
Abstract: front page image
(EN)An apparatus consisting of a variable gain amplifier having an input and an output having a DC-offset compensation loop connected between the output and the input of the variable gain amplifier. The DC-offset compensation loop having a gain independent cutoff frequency.
(FR)L'invention concerne un appareil comprenant un amplificateur à gain variable comportant une entrée et une sortie ayant une boucle de compensation de décalage en continu entre la sortie et l'entrée de l'amplificateur à gain variable. La boucle de compensation de décalage en continu a une fréquence de coupure indépendante du gain.
