Abstract

Cet amplificateur permet d'amplifier de façon convenable les signaux à grande amplitude. L'amplificateur comporte deux paires de transistors qui se shuntent par leurs bases et par leurs collecteurs; les émetteurs interconnectés des transistors d'une paire reçoivent un courant continu à intensité pratiquement constante, tandis que les émetteurs interconnectés des transistors de l'autre paire reçoivent une tension continue essentiellement constante. En fonction de la tension entre les bases, la différence entre les intensités des courants de collecteur de ces paires de transistors offre une allure linéaire même pour des tensions d'entrée plus élevées (50 mV). Application aux récepteurs de télévision.
