Abstract
A delay circuit includes an inverting receiving circuit, a reference point generating circuit, a first buffer gate and a first inverter. An inverting receiving circuit includes a first transistor and a first switching circuit. The reference point generating circuit includes a compensation resistor, a capacitor element, and a first current source. In response to the input signal being at a first potential, a voltage of the output node starts to decrease from a voltage reference point. In response to at least one of a manufacturing process, the first reference voltage, and a temperature being changed, the compensation resistor is configured to correct the voltage reference point.
