Abstract
According to one or more aspects of the present invention, an amplifier arrangement is disclosed. The arrangement comprises a first, a second and a third amplifier. The first and second amplifiers are coupled to one another such that they form a negative feedback loop. In addition, an output node of the first amplifier is connected to a signal input of the third amplifier. An output node of the third amplifier circuit forms the amplifier output of the amplifier arrangement. In addition, the third amplifier circuit is designed for switchably changing its gain on the basis of a signal at an actuating input of the amplifier arrangement.
