Abstract
An electromechanical amplifying method including a transducing an electrical signal to a mechanical resonator having a mechanical resonance mode with an angular frequency ω0; transducing the non-linear oscillations of the resonator into a transduced electrical signal; and filtering the transduced electrical signal to obtain an output signal, the signal transduced to the resonator being obtained by adding a first input signal of a first amplitude and a first angular frequency ωs and a second pump signal of a second amplitude greater than the first amplitude and of a second angular frequency ωs that is different from the first angular frequency, the first and second angular frequencies being close to the angular frequency ω0 of the mechanical resonator and the second pump signal being chosen from a range of angular frequencies ωp and amplitudes in which the resonator is actuated in a non-linear regime.
