Abstract

The invention relates to an arrangement comprising a main amplifier (1, 10) and means (5) for creating, at least during predetermined periods, a floating references voltage (V.sub.G) for applying at least one input signal (V') on at least one first input terminal (E-, E) of the main amplifier, said reference voltage (V.sub.G) being servo-controlled to the equivalent input noise (Vn) of the main amplifier.
