Abstract: An injection locking oscillator (ILO) circuit includes; an injection circuit that receives input signals having a phase difference and provides injection signals respectively corresponding to the input signals based on a voltage level difference between each input signal and an oscillation signal at an output terminal, and a poly-phase signal output circuit that provides poly-phased signals having a phase difference between signals fixed to a defined phase difference upon receiving the injection signals from the input terminals.
