Abstract:
A Phase Locked Loop circuit, includes: a main path through which an input signal is propagated, and an actual signal is output; a main feedback path through which the actual signal is fed back to an input stage of the main path; and a local feedback path through which feedback is carried out from a path middle of the main path to a path middle of an input stage side; the main path including a phase detector, a loop filter, and a controlled oscillator, and the local feedback path including a replica portion, a delay portion, a first subtracter, and a second subtracter.
