Abstract:
1. An amplifier arrangement comprising: a first transistor comprising a first terminal, a second terminal, and a third terminal; a further transistor comprising a first terminal, a second terminal, and a third terminal; a first coupling impedance comprising a coil and that couples a first supply terminal to the second terminal of the first transistor; a further coupling impedance comprising a partial coil and that couples the first supply terminal to the second terminal of the further transistor; an input terminal coupled to the first terminal of the first transistor and the first terminal of the further transistor; a common output node coupled to a second supply voltage terminal, an output terminal, the third terminal of the first transistor, and the third terminal of the further transistor; and an activation/deactivation mechanism comprising at least one selection input, wherein the activation/deactivation mechanism is coupled to the first terminal of the first transistor and the first terminal of the further transistor, wherein the coil of the first coupling impedance comprises at least one winding tap connected to the second terminal of the further transistor.
