摘要： The object of the invention is an improved method and arrangement for processing a signal. The invention can preferably be used for processing analog signals in embodiments wherein it is essential to achieve small energy consumption. By the term signal processing one means, in this context, for example, the summing, difference, integration and differentiation of voltage representing a signal, or charge or current equally well. In the solution according to the invention, charge transfer from signal voltage (U s ) to integrating capacitance (C o ) is exploited by means of charge transfer capacitance (C i ), an active element (T) and controllable switches (S 1 , S 3 ). The operation of the circuit according to the invention is additionally based on the fact that the charge transfer to the charge transfer capacitance (C i ) is terminated when the transistor (T) is in a current-carrying state and that current flow is ensured by means of a constant-current element set according to the invention. According to the invention, 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.
