Abstract
A method for controlling the power supply of an integrated circuit, the power supply comprising a power supply unit powered by a main voltage and possessing several transistor groups, comprising turning on in succession at least two transistor groups in order to deliver, as an output from each group, to at least one part of the integrated circuit, an elementary supply voltage derived from the main voltage, characterized in that the method comprises at least one elementary power phase for supplying power to said at least one part of the integrated circuit, wherein the phase comprises defining voltage thresholds respectively associated with the transistor groups, turning on a first transistor group, the first group delivering a first elementary supply voltage and turning on at least one second group when the first elementary supply voltage is higher than or equal to the voltage threshold associated with the second group.
