Abstract
An injection-locked clock multiplier includes an oscillator control unit configured to output an injection clock signal with a frequency of N times a reference clock signal, an error detector configured to detect a frequency error indicating whether a frequency of the injection clock signal corresponds to the N times the frequency of the reference clock signal in a first operation mode and configured to detect an error due to injection path non-ideality from the injection clock signal in a second operation mode, and an error adjuster configured to receive one of information on the frequency error and information on the error due to the injection path non-ideality from the error detection unit and configured to adjust an operation frequency of the oscillator based on the frequency error or configured to adjust an operation cycle of the oscillator based on the error due to the injection path non-ideality.
