    Abstract: The device resonant comprises a plurality of synchronized oscillators. Each oscillator comprises a resonator which comprises detection means providing detection signals representative of oscillation of the resonator to a feedback loop connected to an excitation input of the resonator. The detection signals control the conductivity of the feedback loop of the oscillator. The excitation inputs of all the resonators are connected to a common point which constitutes the output of the resonant device. A capacitive load is connected between said common point and a reference voltage.

    Abstract: The resonant device comprises an electromechanical resonator of nanometric or micrometric size that comprises a mobile element and a fixed element. Detection means provide detection signals representative of movement of the mobile element with respect to the fixed element to a feedback loop that is connected to an excitation input of the resonator. The resonator is formed on the same substrate as the detection means and feedback loop. The feedback loop comprises at most first and second transistors connected in series between a reference voltage and the excitation terminal. A capacitive load is connected between the excitation terminal and reference voltage. The detection signals control the conductivity of the first transistor.

    Abstract: The oscillator comprises at least a first series of a multiple of four sub-assemblies each of which comprises an excitation terminal and an output terminal. The sub-assemblies are arranged in series in a closed loop. The output terminal of each sub-assembly is connected to the excitation terminal of the following sub-assembly. The output terminal of one of the sub-assemblies constitutes the output terminal of the oscillator. Each sub-assembly comprises excitation means and a nanowire which constitutes the electromechanical resonator and the piezoresistive detection means of movement of the resonator. A first terminal of the nanowire is connected to a first supply voltage. The second terminal of the nanowire constitutes the output terminal of the sub-assembly which is grounded via a corresponding resistive circuit. An input terminal of the excitation means constitutes the excitation terminal of the sub-assembly.
