Abstract
The voltage generator comprises a negative feedback loop including a programmable voltage divider having a feedback node. The voltage divider comprises a programmable resistor disposed between the output of the voltage generator and the feedback node and having variable resistance. The programmable resistor includes a fixed resistor and a plurality of additional resistors arranged in series with each other and defining a plurality of intermediate nodes. The additional resistors may be selectively connected by means of switches disposed between the output of the voltage generator and a respective intermediate node so as to define an output voltage V programmable on the basis of command signals supplied to the switches.
