Abstract
An integrated electronic device includes a sample and hold stage. The sample and hold stage has a sampling capacitor (C) for an input voltage at an input node (Vin), a first switch (S) coupled between the input node (Vin) and the sampling capacitor (C) for connecting the input node (Vin) to the sampling capacitor (C). There is also a voltage follower with an input coupled to the sampling capacitor (C). The first switch (S) includes a first MOS transistor (NM) coupled between the input node (Vin) and the sampling capacitor (C). The first MOS transistor has a bulk. The sample and hold stage is adapted to selectively couple the bulk to a node having a voltage level (V) which is equal or close to the voltage level at the input node of the voltage follower.
