Abstract

See full text

A DLL circuit includes: a time difference amplifier circuit that includes current sources for setting a time difference amplification factor and an input time difference range, and amplifies, to a first signal and a second signal which are input, a time difference between edges which are change points of logic levels respectively included in the first and second signals, using the current sources and outputting a first amplified signal and a second amplified signal obtained; a phase comparison circuit that calculates a phase difference between the first and second amplified signals output and outputs a phase difference signal indicating the phase difference calculated; and a variable delay circuit that delays the second signal by an amount of delay depending on the phase difference indicated by the phase difference signal output from the phase comparison circuit and outputs the delayed second signal as a delayed signal.
