Title (EN) CIRCUIT FOR IMPROVED DIFFERENTIAL AMPLIFIER AND OTHER APPLICATIONS
(FR) CIRCUIT POUR AMPLIFICATEUR DIFFERENTIEL PERFECTIONNE ET D'AUTRES APPLICATIONS
Abstract: front page image
(EN)Differential amplifiers and phase-splitting circuits incorporate voltage-transfer or current-transfer devices of different conductivity types that are connected in series between two different potentials. The current flowing through the two devices is responsive to input signals provided to either or both of the devices. The two devices may be of different types such as bipolar transistors, field-effect transistors, vacuum tubes, triacs and silicon controlled rectifiers. Specific implementations include amplifiers with very low input capacitance and very low second harmonic distortion, multi-state memory cells, detectors and voltage regulators.
(FR)Les amplificateurs différentiels et les déphaseurs multiples comportent des dispositifs de transfert de courant ou de transfert de tension possédant différents types de conductivité, connectés en série entre deux potentiels différents. Le courant circulant dans les deux dispositifs réagissent aux signaux d'entrée envoyés à un des deux dispositifs ou aux deux. Les deux dispositifs peuvent être de types différents, à savoir du type transistor bipolaire, transistor à effet de champ, des tubes à vide, triac et redresseur de courant au silicium. Des mises en oeuvres spécifiques comprennent des amplificateurs à très faible capacité d'entrée et distorsion par harmoniques 2, des cellules de mémoire multi-états, des détecteurs et des régulateurs de tension.
