A protection device includes a first protection stage comprising a first p-type transistor comprising a first terminal, a second terminal, and a first gate terminal. A first voltage regulating device is connected between the first terminal and the second terminal. A second voltage regulating device is connected between the first terminal and the first gate terminal. A third voltage regulating device is connected to the first gate terminal. A first current source is connected to the first gate terminal.

Protection device

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.
