Abstract: A sampling switch circuit, comprising: an input node, connected to receive an input voltage signal to be sampled; a sampling transistor comprising a gate terminal, a source terminal and a drain terminal, the source terminal connected to the input node; a potential divider circuit connected to the input node and a track-control node to provide a track-control voltage signal dependent on the input voltage signal at the track-control node; a hold-control node connected to receive a hold-control voltage signal; an output node connected to the drain terminal of the sampling transistor; and switching circuitry configured to connect the gate terminal of the sampling transistor to the track-control node or to the hold-control node in dependence upon a clock signal.
