Abstract: The invention relates to an integrated self-powered and switching electronic circuit (10) for regulating a stable reference voltage (Vr), comprising a band-gap voltage generator to produce said stable reference voltage (Vr) for a system circuit block (2, 12) that is generally supplied by the output of the band-gap generator through a comparator and an error amplifier. A regulating loop is provided between the output of the system block (12) and the input of the voltage generator circuit (10) to supply a voltage signal (SENSE) produced by the output of the system block. Advantageously, the voltage generator circuit incorporates both the comparator and the error amplifier.
