Offset Voltage Compensated Sampling and Holding Device and Its Operation Method (OFFSET-COMPENSATED SAMPLE AND HOLD ARRANGEMENT AND METHOD FOR ITS OPERATION)

摘要

A sampling and holding device in which offset voltage compensation is compensated includes at least one operational amplifier (A), a first capacitor (C1), a second capacitor (C2), a first switch (S110) 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, The switches, capacitors, and operational amplifiers can be interconnected and switched in such a way that the output voltage varies very little during the offset compensation phase.
