Abstract
A circuit for generating a reference voltage and detecting a drop in a supply voltage, comprising at least one threshold comparator having an input terminal and an output terminal, and a voltage divider connected between a first supply voltage reference and a second voltage reference and connected to the input terminal of the comparator, further provides for the output terminal of said comparator to be connected to the input terminal through at least one feedback network comprising at least one current generator. The feedback network further comprises a buffer block having an input terminal connected to said comparator and a first output terminal connected to a switch which is connected between a circuit node of said voltage divider and the second voltage reference.
