In switch-capacitor systems for extremely low supply voltage, employing a fully differential switched op-amp, proper functioning of nMOS switches coupled to the inverting input node of an integrated stage capable of outputting a common mode control signal is made possible by retaining the ground potential on the input node to prevent body effects on the threshold of nMOS switches by means of an auxiliary switched capacitor.

Abstract
In switch-capacitor systems for extremely low supply voltage, employing a fully differential switched op-amp, proper functioning of nMOS switches coupled to the inverting input node of an integrated stage capable of outputting a common mode control signal is made possible by retaining the ground potential on the input node to prevent body effects on the threshold of nMOS switches by means of an auxiliary switched capacitor.File in questo prodotto:
