A delay circuit comprises a charge/discharge circuit and a logic circuit. The charge/discharge circuit is used to moderate a slope of change of an input signal. The logic circuit receives a charge/discharge signal output from the charge/discharge circuit, and is used to change an output signal of the logic circuit when the charge/discharge signal exceeds a threshold value of the logic circuit. A time constant in the charge/discharge circuit is varied in accordance with the change in the output signal of the logic circuit. This serves to alleviate the malfunctioning and timing constraint problems that occur after the threshold value of the next-stage circuit (logic circuit) is exceeded.
