Abstract: A plurality of MIS charge transfer systems are connected to the output of a first MIS charge transfer system and are operated in parallel with each other. The plurality of charge transfer systems form filters of the same kind, or of a different kind, and charge packets emitted thereby have different delay times and are subsequently converted into a voltage which is sampled at a higher frequency than the sampling frequency for the signal which is applied to the input of the first MIS charge transfer system. This voltage is smoothed by a simple low pass filter.
