  "textContent": "The invention discloses a device for collection of tiny charges in the Nano-Coulomb-range and below, comprising at least one capacitor stack build by n capacitors and 2n switches (nϵN), at least one further capacitor outside the capacitor stack as buffer capacity, at least two additional switches and a DC input source. The n capacitors are dedicated to be sequentially charged by the DC input source one after the other, wherein the 2n switches in the capacitor stack couple the n capacitors sequentially to the DC input source. The at least one further capacitor is dedicated to be charged from the n capacitors of the capacitor stack at once. Furthermore, the invention discloses a method for small charge collection, comprising the steps of sequentially charging the n capacitors of the at least one capacitor stack by coupling one capacitor after the other to the DC input source by selectively closing the switches and discharging the n capacitors of the capacitor stack into at least one further capacitor outside the capacitor stack (nϵN). Additionally, the usage of the device or the method according to the invention to collect charges from sources with electrical potentials of a few millivolts is disclosed.",
