Abstract

La présente invention concerne plusieurs procédés et architectures fondés sur des systèmes microélectromécaniques (MEMS) dans lesquels on utilise des résonateurs micromécaniques vibrants dans des circuits pour effectuer des fonctions de filtrage, de mélange, de référence de fréquence et d'amplification. On décrit un procédé et un appareil utilisés pour générer un signal ayant au moins une fréquence de sortie désirée telle qu'une fréquence d'oscillateur local (LO) dans un sous-système de fréquence radioélectrique en réponse à une tension de réglage et sans l'aide d'un circuit de verrouillage de phase. Un des avantages principaux résultant de telles architectures est lié à une diminution de la consommation de puissance qui entraîne une sélectivité élevée (c'est-à-dire un facteur de qualité (Q) élevé). Par conséquent, la présente invention repose sur l'utilisation d'un grand nombre de liaisons micromécaniques dans des réseaux SSI pour assurer des fonctions de traitement du signal avec une consommation de puissance sensiblement nulle.
