ABSTRACT:
The present invention relates to a reenergizing circuit designed to start a MOS technology integrated circuit. It comprises a power supply terminal, a ground terminal and an output terminal, a first capacitor which is connected between the ground terminal and a circuit node; the capacitor has a charge which is controlled by means of a first p-type transistor which is connected between the power terminal and the circuit node. It further comprises an inverter gate which has a modifiable threshold voltage whose input terminal is connected to the circuit node, an inverter connected between the output terminal of the inverter gate and the output terminal, a current source which is connected in series to a divider circuit controlling the first p-type transistor and a circuit (C) having a transfer function V.sub.S =f (V.sub.E) of the inverter type, said circuit (C) being connected between the output terminal of the inverter gate and the current source in order to control the operation of the current source.
