SYSTEM AND METHOD FOR OPERATING MECHANICAL RESONATOR IN ELECTRONIC OSCILLATOR Russian patent published in 2018 - IPC G04F7/04 

FIELD: measurement technology.

SUBSTANCE: invention relates to a method for operating a mechanical resonator in an electronic oscillator. Method comprises the following steps: determining at least two independent electrically measurable parameters that represent state variables: stiffness, mass and/or a dimension of a crystal resonator; measuring a resonance mode frequency of a crystal with respect to a reference signal frequency; determining a frequency correction factor that is a ratio of the resonance mode frequency and the reference signal frequency; directly or indirectly changing the state variables; logging measurement values of the at least two parameters and the corresponding frequency correction factor in a table; repeating steps b to e a number of times to fill the table.

EFFECT: higher temperature stability.
