Abstract: The protection structure (1) has a plurality of protection regions (2) extending along closed lines arranged inside each other. Each intermediate protection region (2) is tangent to two different adjacent protection regions (2), at different areas (3), such as to form a connection in series with them. The protection structure (1) can be of resistive material, such as to form a series of resistors, or it can include doped portions alternately of P- and N-type, such as to form a plurality of anti-series arranged diodes. The structure can be made of polycrystalline silicon extending on the substrate surface, or can be integrated (implanted or diffused) inside the substrate.

Abstract: The use of a nonlinear multiplier in the control loop of DC-DC converters, SMPS (Switching Mode Power Supply) systems and in PFC (Power Factor Correction) systems, and in particular wherein the constant K of the multiplier circuit vary in function of the amplitude of the error signal fed to an input of the multiplier circuit, greatly enhances stability and immunity to noise, especially that coming from the supply rails.
