ABSTRACT:
Two different set voltages are respectively compared with a power source voltage. When the smaller set voltage which is close to a minimum operating voltage of an arithmetic circuit coincides with the power source voltage, a clock signal generator, and hence the arithmetic circuit are stopped. When the power source voltage increases to coincide with the larger set voltage after the clock signal generator is stopped, the clock signal generator and hence the arithmetic circuit are restarted.
