Patent ID: 8278947

Claim:
A capacitive divider device designed to attenuate an input voltage, said device comprising electrodes on different levels of a multilayer structure separated by insulating layers, said electrodes including a first and second main electrode to apply said input voltage, and a common electrode to supply an attenuated voltage from said input voltage, wherein said first and second main electrodes are on the same level of said structure, the common electrode is on another level of said structure, said common electrode is arranged to form a first capacitive unit with the first main electrode and a second capacitive unit with the second main electrode, wherein said device comprises at least a first auxiliary electrode on yet another level of the multilayer structure and arranged to form a first auxiliary capacitive unit with the common electrode, and wherein said auxiliary electrode and the second main electrode extend towards one side of the multilayer structure to electrically connect said auxiliary electrode to the second main electrode via a linear conductor, said device additionally comprising a plurality of auxiliary electrodes on specific levels of the multilayer structure, each auxiliary electrode arranged to form an auxiliary capacitive unit with the auxiliary electrode on a consecutive specific level, said auxiliary electrodes connected either to the second main electrode or to the common electrode to obtain a parallel connection of each auxiliary capacitive unit with the second capacitive unit.
