Abstract: An amplifying circuit receiving an input voltage and a reference voltage equal to a fraction of the circuit supply voltage, the reference voltage provided by a time constant circuit, including a circuit for, upon power-on, inhibiting the amplifying circuit for as long as the difference between the value of the provided reference voltage and the voltage at the output of the time constant circuit is greater than a determined threshold.
