Abstract: A frequency regulator and a frequency regulating method thereof, and an electronic device are disclosed. The frequency regulator includes: a signal processing circuit configured to generate a frequency control word according to a frequency regulating coefficient and an input frequency; and a frequency regulating circuit configured to receive the frequency control word and to generate and output an output signal having a target frequency according to the frequency control word. The frequency regulating coefficient is an arbitrary positive real number and is expressed as M.m, M is an integer portion of the frequency regulating coefficient and is a natural number, and m is a decimal portion of the frequency regulating coefficient.
