Abstract
A method generates a reference voltage by steps including: generating a reference signal from a voltage source; generating a comparison signal of the reference signal with a voltage reference; sampling the comparison signal; adjusting a numerical value as a function of the result of the comparison and of the numerical value; and converting the current numerical value into a voltage corresponding to the reference voltage.
