The random cosmic-muon trigger makes one problem of the DSC apparent. The value of the baseline is dependent on the elapse-time between triggers. This effect is assumed to arise from a time dependent static charging of the sampling capacitors. The effect varies from chip to chip. The time constant was determined and is a few 100ms. At a constant trigger rate above 50/s the random baseline fluctuation disappears. This problem can be solved by applying an additional "flash frequency" of 100Hz to the DSC. However, for a new version of the chip, this problem will be solved by use of an additional switch, which keeps the sampling capacitors at a constant potential, except for the sampling and the readout phase.
