ABSTRACT:
A charge transfer from signal voltage (U.sub.S) to integrating capacitance (C.sub.O) is accomplished by means of charge transfer capacitance (C.sub.i), an active element (T) and controllable switches (S.sub.61, S.sub.62, S.sub.63, S.sub.64). The operation of the circuit is additionally based on the fact that the charge transfer to the charge transfer capacitance (C.sub.i) is terminated when the transistor (T) is in a current-carrying state and that current flow is ensured by a constant-current element set. These features are combined preferably in such a way that the breaking current of charge transfer is equally great as previously said current of the constant-current element.
