Abstract
In a multi-stage switching-type delay circuit, occurrence of a hazard is inhibited at the time of the switching of the number of stages. With the multi-stage switching-type delay circuit, an input IN of the delay circuit is connected to a stage that is not selected as a path for causing a delay in order to prevent a logic state of each of the internal nodes of the delay circuit from being changed between before and after the switching of the number of stages.
