An electromechanical amplifying method including a transducing an electrical signal to a mechanical resonator having a mechanical resonance mode with an angular frequency &#x3c9;; 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 &#x3c9;and a second pump signal of a second amplitude greater than the first amplitude and of a second angular frequency &#x3c9;that is different from the first angular frequency, the first and second angular frequencies being close to the angular frequency &#x3c9;of the mechanical resonator and the second pump signal being chosen from a range of angular frequencies &#x3c9;and amplitudes in which the resonator is actuated in a non-linear regime.
