Claim:
1. A method for smoothing current consumed by a power supply for an electronic circuit, the electronic circuit comprising at least one module powered by the power supply and consuming a module current, a first current source stage powered by the power supply and comprising at least one main current source, and a terminal stage powered coupled to the first current source stage and powered by the power supply, the method comprising: generating at least one module auxiliary current equal to a first fraction of current consumed by the at least one module; generating by the at least one main current source in the first current source stage a main current higher than a maximum value of the at least one module auxiliary current, with the first current source stage delivering a stage current at least equal to the main current; generating an intermediate current equal to a difference between the stage current and a secondary current equal to the at least one module auxiliary current; and multiplying the intermediate current in the terminal stage by a multiplication factor equal to an inverse of the first fraction incremented by one.
