The delay circuit unit may receive a trigger signal, output a first delay signal obtained by delaying the trigger signal by a first delay time, and output a second delay signal obtained by delaying the trigger signal by a second delay time. The first trigger-correction unit may receive the first delay signal and output a first switch signal obtained by delaying the first delay signal by a first correction time. The second trigger-correction unit may receive the second delay signal and output a second switch signal obtained by delaying the second delay signal by a second correction time. The clock generator may generate a clock signal that is common to the delay circuit unit and the first and second trigger-correction units.
