1. A method comprising:

  • inputting a reference signal through an injection circuit of an oscillator circuit that generates an output signal of high power that oscillates at an inherent frequency of oscillation of the oscillator circuit, the power of the output signal being higher than a power of the reference signal;

    reducing a frequency of the reference signal through a differential transistor pair coupled to the injection circuit of the oscillator circuit; and

    locking through a tuning circuit of the oscillator circuit coupled to the differential transistor pair a frequency of the output signal to the reduced frequency of the reference signal based on the power of the reference signal to amplify the power of the reference signal through the oscillator circuit, the frequency of the reference signal being higher than the frequency of the output signal.
