Preface
The injection-locking or synchronization of an oscillator by an external periodic signal hereafter referred to the injection signal whose frequency is in the proximity of the natural frequency, more specifically the frequency of the first harmonic, of the oscillator under injection shifts the frequency of the oscillator from its natural frequency to the frequency of the injection signal. The frequency of the injection-locking signal can also be either a superharmonic or a subharmonic of the natural frequency of the oscillator under injection to realize frequency division or frequency multiplication. First-harmonic injection-locking achieves frequency synchronization by utilizing the frequency dependence of the amplitude and phase of the output of the oscillators under injection, whereas superharmonic/subharmonic injection-locking achieves frequency-locking by utilizing the internal nonlinear mechanism of the oscillator to generate the desired frequency component and the internal frequency selection mechanism of the oscillator to select the desired frequency component generated by the nonlinear mechanism of the oscillator. The absence of an explicit frequency detector, a charge pump, and a loop filter that typically exist in a frequency-locked loop (FLL
