Abstract:
An amplifier arrangement has an input transistor being connected between reference potential terminals by a current source and a current sink. An amplifier stage has an amplifier output coupled to a first connection node between the current sink and a first terminal of the input transistor by means of a feedback path, and an amplifier input connected to a second connection node between the current source and the second terminal of the input transistor. A level-shifting structure has a level-shifting element with one end connected to a reference connection, wherein the level-shifting element is adapted to perform a level-shifting of a potential at the second connection node with respect to a potential at the reference connection. The reference connection is coupled to one of the following: the amplifier output, the first connection node, a control terminal of the input transistor.
