Abstract

A method and a circuit for scrambling the current signature of a load including at least one integrated circuit executing digital processings, including the step of, at least on the load ground side, combining a current absorbed by a first linear regulator with a current absorbed by at least one capacitive switched-mode circuit with one or several switched capacitances.
