Abstract

An amplifier arrangement with an amplifier arrangement input and an amplifier arrangement output is disclosed. The amplifier arrangement comprises a first transistor and a first ballast resistance, wherein the first ballast resistance connects a first transistor base of the first transistor to a common base terminal at least one second transistor and at least one second ballast resistance, wherein the at least one second ballast resistance connects a second transistor base of the at least second transistor to the common base terminal; and a feedback device comprising a feedback input terminal for sensing at least a base voltage of the first transistor and further comprising a feedback output terminal that is connected to the common base terminal.
