Abstract
L'invention concerne un amplificateur (300) de signaux radiofréquence, comportant : une branche comportant une inductance (L) en série avec un condensateur (CSW) entre des premier (VBAT) et deuxième (GND) noeuds d'alimentation, le point milieu entre l'inductance et le condensateur formant un noeud de sortie (OUT) ; une branche comportant un transistor MOS (302) en série avec un commutateur (SW) entre le noeud de sortie et le deuxième noeud d'alimentation, le commutateur (SW) ayant un noeud de commande relié à un premier noeud (IN1) d'application d'un signal d'entrée (s1), et le transistor MOS (302) ayant sa grille reliée à un deuxième noeud (IN2) d'application d'un signal d'entrée (s2) ; et un circuit (701) de fourniture d'un signal binaire (S (A)) représentatif du signe de la différence (A) entre la tension drain-source (VDS) du transistor (302) et la tension grille-source (VGS) moins la tension de seuil (Vt) du transistor (302).
