The invention relates to power regulation of integrated circuits such as microprocessors. It suggests measuring instantaneous power consumption inside of the integrated circuit ( 13 ), by sensing state changes of the transistors of the units ( 14, 16, 18 20, 22 ) of the circuit. Based on the sensed power consumption, an instantaneous power consumption for the whole circuit may be computed and transmitted to a voltage regulator ( 27 ). The voltage regulator changes the voltage according to the computed power consumption; the regulator may thus precompensate power surges, and limit voltage transients.
