ABSTRACT:
A current supply includes a current mirror arrangement having a feedback circuit. The current supply includes a current mirror input stage connected to a constant current source providing a reference current; a current mirror output stage providing an output current substantially mirroring the reference current; and a feedback circuit feeding back to the current mirror input stage a feedback signal representing perturbations in the output current to cause the output current to more accurately mirror the reference current. In one embodiment, a dummy current mirror output stage substantially mirrors the reference current, and the feedback circuit receives a signal from the dummy current mirror output stage, and in response thereto, supplies the feedback signal to the current mirror input stage to cause the output current to more accurately mirror the reference current.
