Abstract: A circuit comprises a frequency divider coupled to receive an oscillating signal generated by an oscillator and a division ratio and configured to divide the oscillating signal by the division ratio into a clock signal; a temperature compensation circuit configured to measure a temperature of the oscillator and generate a division ratio to be provided to the frequency divider and a first value on the basis of the measured temperature; and a control system configured to control connection between a calibration element and the oscillator based on the first value and the oscillating signal of the oscillator.
