Abstract

Dispositif d'amplification et d'échantillonnage de signaux à grande dynamique. Il comporte trois amplificateurs interconnectés en série, le gain de deux d'entre eux étant susceptible de prendre plusieurs valeurs différentes, des condensateurs de mémorisation pour mémoriser dans un premier stade les tensions de sortie des amplificateurs, ces tensions mémorisées étant appliquées dans un second stade à l'entrée de la chaîne d'amplificateurs et des moyens de commutation commandés par des moyens de sélection. Application à une chaîne d'acquisition de données sismiques par exemple.
