Voltage comparator including at least an insulated gate MOS transistor and analogic/digital converters using the same

摘要

This invention relates to a voltage comparator with an input (Vin) for an analog signal and an output (Vout) for a digital signal, comprising an inverter (P1,IG) which has an input coupled to the comparator input and an output coupled to the comparator output, and comprising at least two MOS transistors (P1,IG) coupled to each other, at least one (IG) of the two MOS transistors being of the floating gate type.
