    Abstract: The circuit has a linear regulator (4`) for supplying a DC supply voltage (Vdd) to an internal load (29) from an external voltage (Vps). Chopper type capacitive clipping supply circuits (5), with switched capacitances, are in parallel with the activated linear regulator. The circuits supply current at the same time as the linear regulator, during an operation phase (D) of the integrated circuit which corresponds to a phase in which a calculating processor which contains the internal load is active.. An independent claim is also included for a method for scrambling the current signature of a load including an integrated circuit.

    Abstract: The generator has an oscillator circuit (2) whose polarization is controlled by an analog polarization circuit (5). The circuit (5) is controlled by a continuous time and amplitude variation signal produced by a sample-and-hold circuit (63). An output signal of an analog signal generator (64) is sampled with pseudorandom instant by the circuit (63) at each time when an output signal of a pseudorandom signal source (61) crosses a threshold fixed by a detector (62) : An independent claim is also included for a method of controlling a pseudorandom number generator.
