<p>1. A zero circuit to operate on power-up, for starting operation of an MOS integrated circuit, characterized in that it comprises first means (1) in order to generate, from a supply voltage (Vcc) of the circuit, a voltage (Vccp) greater than the said supply voltage and a second means (2) in order to measure the difference between the supply voltage and the generated voltage and to generate a signal (S) for zero when the difference reaches a given threshold after the application of the supply voltage.</p> |
