A sample and hold system, for capturing and reading a sequence of traces of an input signal. The sample and hold system comprising a readout device, a controller, and a sample and hold array of unit cells. The controller is configured for controlling the sample and hold system, such that during an acquisition phase a trace of samples is taken from the input signal in an original sample order and such that the samples are held in the unit cells wherein the samples are assigned to the unit cells in an acquisition order, such that during a consecutive readout phase the samples are read out from the unit cells wherein the order in which the unit cells are read out corresponds with a readout order, and such that the acquisition order and/or the readout order differs from trace to trace.

Noise reduction in sample and hold systems

A sample and hold system, for capturing and reading at least one input signal. The system comprises a readout device, a controller, an array of segments comprising a plurality of unit cells and a dummy unit cell, and segment switches between the segments and the readout device. The controller is adapted for controlling the system such that: during an acquisition phase a trace of samples is taken from the input signal and held in the unit cells; during a readout phase the samples in the unit cells or in the dummy unit cells of a segment are read out by readout device; after opening or closing the segment switches the dummy unit cell, is the first cell which is read out by the readout device.
