Abstract:
1. A MEMS resonator comprising: two resonating masses having an anti-phase and in-phase resonance mode, each mode having a resonance frequency; and an anti-phase resonance levering system coupled to the two resonating masses to stiffen and/or dampen the in-phase resonance mode while leaving the anti-phase resonance mode compliant by effectively raising the in-phase resonance frequency above the anti-phase resonance frequency, and potentially creating a large frequency separation between the two resonance modes, so that energy transfer is reduced between the two modes, allowing for robustness to external acceleration, because the in-phase mode is of a higher frequency, wherein the anti-phase resonance levering system comprises a plurality of levers and a plurality of clamped-clamped beams, the plurality of levers coupled to the two resonating masses and to the plurality of clamped-clamped beams via a plurality of springs.
