2130467 9317436 PCTABS00025 Offset-compensated sample and hold arrangement to sample an input signal comprising at least an operational amplifier (A), a first capacitor (C1), a second capacitor (C2), a first switch (S110), a second switch (S211), a third switch (S210), a fourth switch (S111), a fifth switch (S120), a sixth switch (S121), a seventh switch (S220) and an eighth switch (S221), which switches, capacitors and operational amplifier are interconnected in such a way and may be switched in such a way that during an offset-compensation phase the output voltage will only experience a very small voltage change.
