Abstract

La présente invention concerne une section de modulation d'impulsion qui génère un signal de modulation d'impulsion par modulation d'impulsion et amplifie le composant d'amplitude d'un signal d'entrée. Un filtre passe-bas filtre le signal de modulation d'impulsion de la section de modulation d'impulsion et génère un signal d'amplitude amplifié ayant le composant d'amplitude amplifié. Une section de correction d'erreur génère un signal d'amplitude corrigé en corrigeant l'erreur du signal d'amplitude amplifié du filtre passe-bas en utilisant le composant d'amplitude du signal d'entrée. Une section de synthétisation génère un signal de sortie en synthétisant le signal d'amplitude corrigé de la section de correction d'erreur et le composant de phase du signal d'entrée.
