An amplifier with a non-linear current mirror comprises an amplification stage having an input terminal for an input signal as well as an output stage coupled to the amplification stage by a current mirror stage. The current mirror stage comprises at least one mirror transistor coupled to the amplification stage and at least one output transistor coupled to the output stage. The amplifier comprises two variable resistive elements, each of them connected in series to one of the mirror transistor and the output transistor. A tuning stage is adapted to tune the variable resistive elements in response to the input signal.
