摘要
Methods and systems for providing stable and accurate low noise DC reference voltage are described. In the described embodiments, a feedback controlled DC reference voltage supply provides a stable and well controlled sense current. The sense current is in turn used to produce a stable and well controlled light output from a light emitting diode (LED).
