Abstract
(EN) Exemplary embodiments are directed to systems, devices, and methods for enhancing a telescopic amplifier. An amplifier may include a differential pair of input transistors including at least one transistor configured to receive a first input and at least one other transistor configured to receive a second input. The amplifier may further include a cascode circuit including a first pair of transistors coupled to the at least one transistor of the differential pair to form a first plurality of current paths configured to generate a first output. The cascode circuit maymo also include a second pair of transistors coupled to the at least one other transistor of the differential pair to form a second plurality of currents paths configured to generate a second output.
(FR) Selon des modes de réalisation illustratifs, la présente invention concerne des systèmes, des dispositifs et des procédés pour améliorer un amplificateur télescopique. Un amplificateur peut comprendre une paire différentielle de transistors d'entrée comprenant au moins un transistor configuré pour recevoir une première entrée et au moins un autre transistor configuré pour recevoir une seconde entrée. L'amplificateur peut en outre comprendre un circuit cascode comprenant une première paire de transistors couplés à au moins un transistor de la paire différentielle pour former une première pluralité de chemins de courant configurés pour générer une première sortie. Le circuit cascode peut également comprendre une seconde paire de transistors couplés à au moins l'autre transistor de la paire différentielle pour former une seconde pluralité de chemins de courants configurés pour générer une seconde sortie.
