Abstract
A frequency generating device and an operation method thereof are provided. The frequency generating device includes an oscillator circuit and a processor circuit. The oscillator circuit is configured to generate a clock signal and adjust a clock frequency of the clock signal according to a control voltage. The processor circuit is coupled to the oscillator circuit and is configured to generate the control voltage. The processor circuit reads a frequency aging rate value and a control voltage slope of the oscillator circuit from the oscillator circuit, calculates a control voltage regulation rate value corresponding to the frequency aging rate value and the control voltage slope, and compensates the control voltage based on the control voltage regulation rate value. Alternatively, the processor circuit reads the control voltage regulation rate value from the oscillator circuit, and compensates the control voltage based on the control voltage regulation rate value.
