A resonant filter including a matrix of n&#xd7;m resonators of N/MEMS type, each resonator including an actuating mechanism and a detection mechanism. An input of the filter, configured to receive an electrical input signal, is electrically connected to the resonator actuating mechanism. The outputs of the resonator detecting mechanism are electrically connected together and to an output of the filter, such that the signal to be obtained as an output of the filter is an image of the sum of the mechanical responses of the resonators. The resonators are not mechanically coupled together.

Resonant filter based on an N/MEMS matrix

An array of coupled resonators including: an input unit that supplies an input electrical signal; an electrical excitation unit that electrically excites N coupled resonators of the array using the input electrical signal, wherein the electrical excitation unit includes, for each of the N coupled resonators, an actuator, connected to the input unit, that actuates a respective one of the N coupled resonators according to the input electrical signal, and a variable gain input amplifier that amplifies actuation of a respective one of the N coupled resonators; and a controller that controls a specific setting of a variable gain of each of the variable gain input amplifier.
