Patent ID: 8614609

Claim:
A resonant filter comprising: at least two matrices, having different frequency responses, each matrix comprising, n×m resonators of the N/MEMS type with substantially similar dimensions and distributed in n rows and m columns, with n and m being integers strictly greater than 1, including for each resonator: actuating means for exciting the resonator by controlling an input electric signal of the filter, means for detecting movements of the resonator and for delivering an electrical output signal whereof the value depends on the detected movements; an input of the filter, configured to receive an electrical input signal of the filter, being electrically connected to the actuating means of all of the resonators, the outputs of the detecting means of all of the resonators being electrically connected to each other and to an output of the filter, the resonators not being mechanically coupled to each other, and wherein nominal dimensions of the resonators of one matrix are different from nominal dimensions of the resonators of another matrix.
