    摘要: A method of manufacturing a damping device, for damping vibrations and/or absorbing shocks, and the corresponding device are disclosed, the method comprising the steps of:
    S1) Implementing an Additive Manufacturing step to produce a monolithic structure comprising a first flexible element (1) and at least a second flexible element (2) extending parallel to the first flexible element (1), wherein at least the first flexible element (1) comprises through-going apertures (6),
    S2) Providing a material, in the region between the first flexible element (1) and the at least second flexible element (2), which is able to change of physical and/or chemical state to turn into a viscoelastic material when it is submitted to a suitable predefined treatment, and
    S3) Applying the suitable predefined treatment to the material to conform a dissipative layer (3) of viscoelastic material, extending between the first flexible element (1) and the at least second flexible element (2) and secured to both of them, wherein the through-going apertures (6) are at least partially filled by said viscoelastic material.

    摘要: The present invention concerns an oscillator (100) arranged to output an oscillator carrier and comprising:
    - a tank circuit (20, 30),
    - an active circuit (10) connected to the tank circuit (20, 30), the active circuit (10) comprising transistors (T1, T2), each transistor comprising a terminal (B1, B2), said terminal (B1, B2) allowing to modify a threshold voltage of the transistor (T1, T2).
    According to the invention, the oscillator (100) comprises a control circuit arranged to modify the voltage at the fourth terminal (B1, B2) of at least a subset of said transistors (T1, T2), so as to minimize a phase difference between the oscillator carrier and a device current of the active circuit (10), thereby minimizing low frequency noise to phase noise conversion.
