ABSTRACT:
A delay circuit has a circuit structure dominated by an NMOS or a PMOS transistor. The delay circuit is supplied with, as a power supply voltage, an output voltage of a power supply voltage step-down circuit having a level generating circuit for generating a reference voltage obtained by an offset voltage and a manufacturing variation dependent voltage, and an m-time voltage generating circuit. A semiconductor device includes the delay circuit.
