Abstract: Provided is an apparatus for measuring an input time of an input signal, and more particularly, an apparatus for measuring an input time of an input signal more precisely than a reference clock using a delay circuit. The apparatus for measuring an input time of an input signal includes: a signal input unit receiving a signal; a clock generation unit generating a reference clock; a delay unit including at least one delay circuit generating at least one delayed clock by delaying the reference clock; a detection unit detecting a signal input from the signal input unit, depending on a clock signal input from the clock generation unit and delay circuits; and an operation unit operating an input time of an input signal from the signal input unit based on data detected by the detection unit.
