摘要: 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.

摘要: A quartz crystal resonator is connected to an array of switchable capacitors or resistors. The switched actuation of elements of the array is controlled by bits of a control word. At least one of the bits of the control word is controlled by pulse width modulation to effectuate a tuning of the oscillation frequency of the quartz crystal resonator.
