Abstract
The input voltage (V.sub.e) of the device is constituted by the superposition of a direct voltage (V.sub.0) and a time-varying sampled voltage (v.sub.e). Subtraction means comprising storage and transfer electrodes, and diodes, establish the difference between the quantity of charges which is double the quantity corresponding to the direct voltage (that is, 2Q.sub.moy) and the quantity of charges corresponding to each sample of the variable voltage superposed on the direct voltage (that is, Q.sub.moy .+-.q.sub.e).
