1. Device for charge collection comprising
at least one capacitor stack built by n capacitors and 2n switches;
at least one further capacitor outside the at least one capacitor stack as buffer capacitor;
at least two additional switches outside the at least one capacitor stack;
a DC input source;
a CMOS-Logic;
wherein the 2n switches of the at least one capacitor stack couple the n capacitors selectively to the DC input source;
wherein the n capacitors of the at least one capacitors stack are dedicated to be sequentially charged by the DC input source one after the other;
wherein the at least one further capacitor outside the at least one capacitors stack is dedicated to be charged from the n capacitors of the capacitor stack at once; and
wherein n∈N.
