Abstract
Disclosed is a current mirror which maintains good performance when the current to be tracked corresponds to a voltage close to the low supply voltage. This current mirror includes a feedback circuit which causes the first transistor of the reference branch of the mirror to track the voltage of the second transistor of the output branch of the mirror.
