Abstract
Here, a driver for an light emitting diode (LED) is provided. Within this driver, several differential pairs of bipolar transistors are employed in an input stage and output stage along with a control loop. Collectively, these components operate together to drive the LED with a low headroom voltage while still achieving high driver performance in terms of edge speed and jitter.
