Abstract

PURPOSE:To obtain a prescribed voltage after the application of power supply in a short time, by applying an output of an oscillation circuit which is operated at the supply of power voltage to a charge pump capacitor and obtaining a boosted voltage. CONSTITUTION:An oscillation circuit OSC starts oscillation when a power supply voltage Vcc is applied. When a potential of a node N2 is at low level, an FETQ3 turns on and a capacitor C4 is charged up to about (Vcc-Vth). The Vth is the threshold value of the FET. When the node N2 is at high level, a node N3 increases to the power supply potential and an FETQ4 turns on, then a capacitor C5 is charged up to the power supply potential or more. At this time, the FETQ3 turns off in inverse bias. Through the repeated operation mentioned above, a voltage which is the power supply voltage Vcc or more is outputted to the node N4.
