ABSTRACT:
A current amplifier has an input terminal (1) for an input current (Iin) to be amplified in order to obtain a first output current (Iout1) at a first output terminal (2) via a first transistor (T1) and a second output current (Iout2) at a second output terminal (8) via a current mirror (6). A diode-connected transistor (T5) is coupled between the emitter of the first transistor and the input terminal of the current amplifier so as to improve the current branching at the input terminal, thereby extending the bandwidth and the output swing of the current amplifier.
