Injection-locked frequency divider
An injection-locked frequency divider is provided and which includes an injection transistor, an oscillator, a current source and a transformer. The injection transistor is used to receive an injection signal. The oscillator is used to divide the injection signal to generate a divided frequency signal. The current source is coupled to the oscillator to provide a current to the oscillator. The transformer is coupled between the injection transistor and the oscillator to increase the equivalent transconductance of the injection transistor, and thus increasing the locking range of the injection-locked frequency divider.
