摘要：
An injection locking clock generator can vary the free running frequency of an injection locking oscillator to broaden an operating frequency range of an oscillation signal injected to itself, thereby performing an injection locking with respect to all frequencies of an operating frequency range. The clock generator includes a main oscillator configured to generate oscillation signals of a frequency corresponding to a control voltage, and an injection locking oscillator configured to generate division signals synchronized with the oscillation signals by dividing the oscillation signals, wherein a free running frequency of the injection locking oscillator is set according to the frequency of the oscillation signals.
