Abstract

This invention relates to a voltage comparator with an input for an analog signal and an output for a digital signal, comprising an inverter which has an input coupled to the comparator input and an output coupled to the comparator output, and comprising at least two MOS transistors coupled to each other, at least one of the two MOS transistors being of the floating gate type.
