Current amplifier.

摘要

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) improves the current branching at the input terminal, thereby extending the bandwidth and the output swing of the current amplifier.
