The present invention pertains to the field of amplifiers, and relates to an electromechanical amplifying method comprising at least one first transducing step consisting in transducing an electrical signal to a mechanical resonator having a mechanical resonance mode with an angular frequency ω0, the electrical signal actuating non-linear oscillations of the resonator; a second transducing step consisting in transducing the non-linear oscillations of the resonator into a transduced electrical signal; and a filtering step consisting in filtering the transduced electrical signal to obtain an output signal. The method is characterized in that the signal transduced to the resonator is 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 ωρ that is different from the first angular frequency, the first and second angular frequencies being close to the angul
