ABSTRACT:
A delay circuit includes: an input signal line (IN) through which an input signal is inputted; a capacitor (106) charged with and discharging electric charge; a first switch (101) connected to the input signal line and operating according to the input signal when the capacitor is to be charged with electric charge; a second switch (102) connected to the input signal line and operating according to the input signal when the electric charge is to be discharged from the capacitor; and a comparison circuit (107) comparing a voltage of the capacitor and a reference voltage to output a delay signal of the input signal.
