Abstract:
1. A voltage regulator for providing an operating voltage to an integrated circuit formed on a same chip as said voltage regulator, said voltage regulator comprising: a voltage down-converter arranged to convert a chip-external supply voltage to the operating voltage based on a signal indicative of a desired value of the operating voltage and output the operating voltage; an adjustable signal generator for adjustably generating the signal indicative of the desired value of the operating voltage; a detector for measuring at least one electrical or operational parameter of the integrated circuit when the integrated circuit is operated at a nominal voltage; and an evaluator to determine the desired value of the operating voltage based on the parameter(s) measured by the detector when the integrated circuit is operated at the nominal voltage and to supply a signal to the signal generator indicative of the desired value.
