    Abstract: A method of calibrating an oscillator in order to compensate the dispersions generated, on the one hand, during the process of fabricating the oscillator circuit components and, on the other hand, by variations of operating conditions by modifying the parameters of a resonant component, for example a capacitor or an induction coil of the oscillator, in order to change the frequency range covered by the oscillator, according to the control voltage. Accordingly, calibrating the oscillator adjusts the output frequency of the oscillator according to an oscillator control signal. The calibration device determines the difference between the output frequency of the oscillator divided by a quantity and a reference frequency of the oscillator. The device includes a set of impedances selectively connected to the oscillator and each corresponding to a frequency deviation of the oscillator, and a calibration stage to generate a calibration word according to the measured frequency difference.
