Abstract

A variable delay circuit has a positive logic variable delay circuit which delays an edge of a signal which is input through an input terminal and a negative logic variable delay circuit which delays an edge of the signal input through an input terminal. Only an edge delayed in accordance with the set time is extracted from all the edges of a signal supplied from the positive logic variable delay circuit and all the edges of a signal supplied from the negative logic variable delay circuit in an extracting circuit of the variable delay circuit.
