Abstract:
A current mirror comprising:a first terminal for receiving an input current;a second terminal for supplying an output current;a common terminal;a first transistor having:a control electrode, anda main current path arranged between the first terminal and the common terminal;a second transistor having:a control electrode connected to the control electrode of the first transistor, anda main current path arranged between the second terminal and the common terminal,characterized in thatthe current mirror further comprises:a transconductance stage having:an input terminal coupled to the first terminal, andan output terminal coupled to the common terminal; anda bias source that is independent of the input current, and is configured to bias the control electrode of the first transistor and the control electrode of the second transistor to a bias voltage that differs from a voltage at the common terminal.
