Abstract

A powering circuit to start up a MOS technology integrated circuit consists of first means made up of an oscillator and a voltage-increasing device to generate, from a supply voltage, a voltage greater than said supply voltage, and second means to measure the difference between the supply voltage and the generated voltage and to generate a powering signal when the difference reaches a given threshold.
