Abstract
A quartz crystal resonator is coupled to an electronic circuit. A capacitive or resistive element is provided for adjusting a frequency of the quartz crystal resonator on activation or deactivation of a function of a circuit. Control is made according to a model of an expected variation of a temperature of the quartz crystal resonator.
