ABSTRACT:
According to an embodiment of the present invention, a system is provided for driving at least one light-emitting diode (LED). The system includes an output terminal connectable to an anode of the LED and at which an output voltage can be provided for the LED. A driver loop, connectable to a cathode of the LED, is operable to maintain a LED current flowing through the LED at a desired level, thereby attenuating modulation error attributable to voltage variations at the cathode of the LED.
