Low consumption voltage regulator for a high voltage charge pump, voltage regulation method, and memory device provided with the voltage regulator

摘要

A voltage regulator for a regulated voltage generator configured to generate an operating voltage and including a variable comparison voltage generator, a comparison voltage, a partition branch including a plurality of active devices of a resistive type to receive the operating voltage and supply an intermediate voltage correlated to the operating voltage, and a comparator, to receive the comparison voltage and the intermediate voltage and supply a regulation signal for the regulated-voltage generator.
