Abstract
A method, an apparatus and/or a system of injection locking based power amplifier is disclosed. A method includes 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 method also includes reducing a frequency of the reference signal through a differential transistor pair coupled to the injection circuit of the oscillator circuit. The method further includes 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 is higher than the frequency of the output signal.
