Abstract

The invention concerns an amplifier circuit which comprises an amplifier unit (210) arranged to receive an input signal, to influence the amplification of this input signal and to transmit an output signal. The amplifier circuit also comprises a first control unit (210) and a second control unit (220). Those control units receive said output signal. Furthermore, the amplifier circuit comprises a selector unit (240) which is arranged to receive first and second control signals from the control units (310, 220). The selector unit (240) is arranged to control the amplification of the amplifier unit (201) in accordance with that one of said first and second control signals which gives the lowest amplification.
