We obtain an analytic expression for the dependence of the relative error of frequency measure on the precision characteristics of this measure, time intervals of measurements, and periods between the measurements. This expression is characterized by the variance and the systematic component.
A novel strategy to compensate for frequency drifts caused by stiffness changes in resonant microstructures is presented. The proposed compensation method is based on a controlled stiffness modulation of the resonator by an additional feedback loop and extracting the frequency changes caused by the modulated stiffness. The feasibility of the suggested method is verified experimentally by compensating...
