Abstract
A current mirror includes first and second transistors each having a control terminal and a load path with two terminals. The control terminals of the first and second transistors and one of the terminals of the load path of the first transistor receive a first input current. Third, fourth and fifth transistors each have a control terminal and a load path with two terminals. The control terminals of the third, fourth and fifth transistors and one of the terminals of the load path of the third transistor receive a second input current of equal magnitude to the first input current. One of the terminals of the load path of the fifth transistor supplies an output current proportional to the two input currents. The other of the terminals of the load paths of the third and fifth transistors are each connected to one terminal of the load path of a respective one of the fourth and second transistors. The other of the terminals of the load paths of the first, second and fourth transistors are connected to a common reference point.
