ABSTRACT:
A semiconductor integrated circuit device includes: a first inverter constituted by a first transistor configured to charge a charge point based on an input signal, and a second transistor configured to discharge a discharge point based on the input signal; a P-type third transistor and an N-type fourth transistor with drain-source paths provided in parallel between the charge point and the discharge point; and a second inverter configured to invert a potential of the charge point or the discharge point and supply the inverted potential to gates of the third and fourth transistors, and obtain a delay signal of the input signal from the charge point or the discharge point. The semiconductor integrated circuit device secures a sufficient delay time with a small area.
