Abstract
An injection locked phase locked loop includes an injection locked oscillator configured to generate an oscillation signal according to an injection signal and to generate a replica signal by replicating the oscillation signal when the injection signal is deactivated; a phase controller configured to generate a phase control signal according to a phase error signal; and an error detector configured to generate the phase error signal by comparing a phase of the oscillation signal and a phase of the replica signal, and to control a phase difference between the oscillation signal and the replica signal according to the phase control signal.
