Claim 12:
13. A method implemented by a driver system, the method comprising:
receiving, with a mirror transistor, current from a current source;
receiving, with at least two driving transistors coupled in parallel, current from the mirror transistor;
receiving, with a first light emitting diode (LED) and a first modulator eoupled in series, 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
receiving, with a second LED and a second modulator coupled in series,
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.
