Abstract
A device for compensating for the frequency of a resonator includes (a) a temperature sensor, (b) a sequencer determining a second compensation signal on the basis of the temperature and corresponding to a positive value N, and a third compensation signal on the basis of the temperature corresponding to a ratio between a positive integer S and N, S being lower than or equal to N, and (c) a variable counter receiving the compensation signals and generating a fourth output signal every N periods of a clock signal from the resonator and generating a fifth signal for modifying the charge capacity of the resonator.
