Abstract: In an embodiment a differential pair for an input stage includes two identical branches in parallel, each branch including a first MOS transistor and a second MOS transistor arranged in series, wherein the first transistor and the second transistor have a channel of the same type, and wherein each of the first transistor and the second transistor has a gate coupled to the same corresponding input of the differential pair and a circuit configured to apply to each of the first transistors a potential difference between a source and a channel-forming region of the first transistor.

Abstract: The present disclosure relates to an electronic device comprising a pair of first transistors, each first transistor being coupled to a first node by a conduction terminal, a pair of second transistors, each second transistor being coupled to a second node by a conduction terminal, and a third transistor coupling the first and second nodes, the control terminal of the third transistor being coupled to the output of an operational amplifier, the operational amplifier being coupled, at its input, to the first node and to a node of application of a reference voltage.
