<p>PROBLEM TO BE SOLVED: To provide a clock generator, an electronic apparatus, a mobile body, and a clock generation method that can generate a clock signal having a relatively high frequency stability while reducing wasteful power consumption.SOLUTION: A clock generator 1 measures a frequency ratio between a clock signal CK1 (32.768 kHz+α) and a reference frequency value with reference to a clock signal CK3 (25 MHz), generates a clock signal CK2 having a masked part of clocks of the clock signal CK1 on the basis of a measurement result of the frequency ratio, and controls a measurement interval of the frequency ratio on the basis of a difference between the measurement result of the frequency ratio and N (N is a natural number) average values of the measurement result of the frequency ratio.</p> |
