Abstract
An integrated self-powered and switching electronic circuit regulates a stable reference voltage and comprises a band-gap voltage generator to produce said stable reference voltage for a system circuit block 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 and the input of the voltage generator circuit to supply a voltage signal produced by the output of the system block. Advantageously, the voltage generator circuit incorporates both the comparator and the error amplifier.
