Abstract
Disclosed herein are embodiments of a precharge sample-and-hold circuit. The circuit has an input terminal, a reference voltage terminal and an output terminal. Further, the circuit has a sampling capacitance coupled between the input terminal and the reference voltage terminal and configured to provide the sample voltage when said sample-and-hold circuit is in a holding mode and a cancellation capacitance. Implementations of a precharge sample-and-hold circuit and of methods to operate a precharge sample-and-hold circuit in an analog/digital converter are also disclosed.
