Abstract
An injection-locked frequency divider (ILFD) including a signal injector, an oscillator (OSC), and a buffer stage is provided. The signal injector is configured for receiving an injection signal. The OSC is configured for dividing the frequency of the injection signal, so as to generate a first divided frequency signal, where there is an integral-multiple relation between the frequency of the first divided frequency signal and that of the injection signal. The buffer stage is configured for receiving and boosting the first divided frequency signal, and performing a push-push process on the first divided frequency signal, so as to output a second divided frequency signal, where there is a fractional-multiple relation between the frequency of the second divided frequency signal and that of the injection signal.
