| Zusammenfassung: | A frequency synthesizer includes a delay unit, a phase loop, a control unit, and a frequency divider. The delay unit is utilized for receiving a reference signal and delaying the reference signal according to a delay parameter, so as to generate a delay reference signal. The phase loop is utilized for generating an output signal according to the delay reference signal and a feedback frequency dividing signal. The control unit is utilized for generating the delay parameter and a frequency dividing parameter according to a target magnification factor. The frequency divider is utilized for dividing the frequency of the output signal according to the frequency dividing parameter. |
