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. The optical semiconductor element has a first optical waveguide region and a second optical waveguide region. The precharge circuit charges a precharge node from the clock signal when the data input signal is low and the clock input is high. A transmission and a phase are altered in a 2D simulation based on this first size until a shape dependent transmission and a shape dependent phase allow the 2D simulation to substantially match the 3D simulation. , the formation of the strip, the relevant roller must be rotated into a position wherein the printing machine operator can have access to the ink stripe. The injection needle has a proximal end attached to the needle control handle, a distal region within the tip section, and an open distal end.
