Abstract:
1. A MEMS resonator comprising: a resonator body made of a material having a Young's modulus; an actuation electrode configured to drive the resonator into a resonant mode, wherein the actuation electrode is separated from the resonator body by a non-conductive gap, such that a gap capacitance is defined between the actuation electrode and the resonator body; and an actuation terminal to which an actuation electrode signal is applied, wherein a capacitance between the actuation terminal and the resonator body, which includes the gap capacitance, includes a structure having a first dependence of effective dielectric constant with temperature over an operating temperature range of the MEMS resonator which is equal in sign to a dependence of the Young's modulus of the material of the resonator body with temperature over said operating temperature range.
