Abstract
An injection-locked oscillator includes an oscillator and an injection circuit. The oscillator includes a first oscillation node through which a first oscillation signal is output and a second oscillation node through which a second oscillation signal is output, the second oscillation signal having a phase opposite to that of the first oscillation signal. The injection circuit provides an injection current between the first oscillation node and the second oscillation node according to a reference signal. The injection circuit includes a charging element configured to be charged or discharged in response to a reference signal and to provide the injection current between the first oscillation node and the second oscillation node.
