Several MEMS-based methods and architectures which utilize vibrating micromechanical resonators in circuits to implement filtering, mixing, frequency reference and amplifying functions are provided. For example, a method and apparatus for selecting at least one desired channel in an RF receiver subsystem is shown. One of the primary benefits of the use of such architectures is a savings in power consumption by trading power by high selectivity (i.e., high Q). Consequently, the present invention relies on the use of a large number of micromechanical links in SSI to VLSI networks to implement signal processing functions with basically zero DC power consumption.

L'invention concerne des procédés et architectures basés sur MEMS qui utilisent des résonateurs micromécaniques vibratoires dans des circuits pour effectuer le filtrage, le mixage, le référencement des fréquences et pour remplir les fonctions d'amplification, par exemple, un procédé et appareil pour sélectionner au moins un canal désiré dans un sous-système de récepteur RF. Un des premiers avantages qu'offre l'utilisation de ce type d'architectures est l'économie d'énergie grâce aux échanges d'énergie par haute sélectivité, à savoir par Q élevé. L'invention concerne en outre l'utilisation d'un nombre élevé de liens micromécaniques entre les réseaux SSI et VLSI, qui permettent de remplir les fonctions de traitement de signaux avec une consommation CC proche de zéro.
