Abstract

A sample and hold system (100), for capturing and reading at least one input signal (110). The system (100) comprises a readout device (150), a controller (140), an array (120) of segments (125) comprising a plurality of unit cells (130) and a dummy unit cell (139), and segment switches (160b) between the segments (125) and the readout device (150). The controller (140) is adapted for controlling the system (100) such that: during an acquisition phase a trace of samples is taken from the input signal and held in the unit cells (130); during a readout phase the samples in the unit cells (130) or in the dummy unit cells (139) of a segment (125) are read out by readout device (150); after opening or closing the segment switches (160b, 160c) the dummy unit cell (139), is the first cell which is read out by the readout device (150).
