1. A driver system, comprising:
a mirror transistor coupled to a current source;
at least two driving transistors coupled in parallel and configured to mirror current in the mirror transistor;
a first light emitting diode (LED) and a first modulator coupled in series and configured to receive a first current from one of the at least two driving transistors, a first end of the first LED directly coupled to one of the at least two driving transistors, a second end of the first LED directly coupled to a first end of the first modulator, a second end of the first modulator coupled to a low rail; and
a second LED and a second modulator coupled in series and configured to receive a second current from another of the at least two driving transistors, a first end of the second LED directly coupled to the other of the at least two driving transistors, a second end of the second LED directly coupled to a first end of the second modulator, a second end of the second modulator coupled to the low rail, the first LED configured to emit light having a first color, the second LED configured to emit light having the first color.
