摘要：An oscillator and a self-calibration method thereof are provided. The oscillatorincludes: an oscillation unit for generating an oscillation signal; a converting unit forconverting frequency of the oscillation signal into a voltage signal; a comparison unit for

comparing the voltage signal with a first voltage corresponding to a higher frequencyand a second voltage corresponding to a lower frequency, and outputting a comparisonresult signal; an adjusting unit for storing a calibration value, adjusting the calibrationvalue based on the comparison result signal and outputting a calibration signal

corresponding to the adjusted calibration value; and a calibration unit for calibrating thefrequency of the oscillation signal based on the calibration signal. Self-calibration for thefrequency of the oscillation signal may be achieved, which may ensure the stability of thefrequency of the oscillation signal.
