Abstract

PURPOSE:To achieve a reset output not affected with the rising characteristics of a power supply voltage, by connecting a capacitor to a connecting point of switches in series connection driven complementarily and a switch output, and taking the voltage of a capacitor connected to the output as reset output through detection. CONSTITUTION:A power supply is applied and given to a terminal 1. When the voltage reaches a specified voltage, a clock pulse is generated and this clock pulse turns on switches 6, 7 complementarily. Thus, the terminal voltage of a capacitor 9 is stepwise increased every time the clock pulse is applied. A reset output can be obtained at an output terminal 5 until this voltage exceeds the threshold level of a gate circuit 4.
