Abstract
A delay circuit contains a first inversion circuit including a pull-up circuit and a pull-down circuit, and a second inversion circuit including a pull-up circuit and a pull-down circuit. The delay circuit further contains a first pass transistor connected in series to the pull-up circuit in the first inversion circuit between a power supply potential and an output node, a second pass transistor connected in series to the pull-down circuit in the first inversion circuit between a ground potential and the output node, a third pass transistor connected in series between the input node and the pull-up circuit in the second inversion circuit, and a fourth pass transistor connected in series between the input node and the pull-down circuit in the second inversion circuit. A delay characteristic of the delay circuit is changed by a combination of control signals applied to gates of the pass transistors.
