Title (EN) CURRENT MIRROR
(FR) MIROIR DE COURANT
Abstract:
(EN) A current-mode power amplifier is disclosed. In some embodiments, the power amplifier may include a first cascode transistor pair including a first transfer function coupled to a second cascode transistor pair including a second transfer function. The first transfer function may be an inverse of the second transfer function. The current-mode power amplifier may also include an inductive-capacitive (LC) resonant circuit to reduce the effects of gate capacitances of the first cascode transistor pair and the second cascode transistor pair. In some embodiments, the current-mode power amplifier may include a bias current controller. The bias current controller may adjust transistor bias currents based, at least in part, on an input signal received by the current-mode power amplifier.
(FR) L'invention concerne un amplificateur de puissance en mode courant. Dans certains modes de réalisation, l'amplificateur de puissance peut comprendre une première paire de transistors cascode comprenant une première fonction de transfert, couplée à une seconde paire de transistors cascode comprenant une seconde fonction de transfert. La première fonction de transfert peut être l'inverse de la seconde fonction de transfert. L'amplificateur de puissance en mode courant peut également comprendre un circuit résonnant à inductance-capacité (LC) pour réduire les effets de capacités de grille de la première paire de transistors cascode et de la seconde paire de transistors cascode. Dans certains modes de réalisation, l'amplificateur de puissance en mode courant peut comprendre un dispositif de commande de courant de polarisation. Le dispositif de commande de courant de polarisation peut ajuster des courants de polarisation de transistors sur la base, au moins en partie, d'un signal d'entrée reçu par l'amplificateur de puissance en mode courant.
