Title (EN) VOLTAGE SAMPLER DRIVER WITH ENHANCED HIGH-FREQUENCY GAIN
(FR) CIRCUIT D'ATTAQUE À ÉCHANTILLONNAGE DE TENSION À GAIN HAUTE FRÉQUENCE AMÉLIORÉ
Abstract:
(EN) Methods and systems are described for receiving, at an input differential branch pair, a set of input signals, and responsively generating a first differential current, receiving, at an input of an offset voltage branch pair, an offset voltage control signal, and responsively generating a second differential current, supplementing a high-frequency component of the second differential current by injecting a high-pass filtered version of the set of input signals into the input of the offset voltage branch pair using a high-pass filter, and generating an output differential current based on the first and second differential currents using an amplifier stage connected to the input differential branch pair and the offset voltage branch pair.
(FR) L'invention concerne des procédés et des systèmes pour recevoir un ensemble de signaux d'entrée au niveau d'une paire de branches différentielles d'entrée et générer en réponse un premier courant différentiel, recevoir un signal de commande de tension de décalage au niveau d'une entrée d'une paire de branches de tension de décalage et générer en réponse un second courant différentiel, compléter une composante haute fréquence du second courant différentiel par injection d'une version filtrée passe-haut de l'ensemble de signaux d'entrée dans l'entrée de la paire de branches de tension de décalage à l'aide d'un filtre passe-haut, et générer un courant différentiel de sortie sur la base des premier et second courants différentiels à l'aide d'un étage amplificateur connecté à la paire de branches différentielles d'entrée et à la paire de branches de tension de décalage.
