Abstract
Devices, systems, and methods for improving a current spread of a light emitting diode (LED). Some aspects including a peak detector and a variable gain amplifier coupled to the peak detector and configured to amplify an output of the peak detector. The variable gain amplifier controlled by a gain selector, coupled to the variable gain amplifier by varying the gain of the variable gain amplifier based on an on time of a signal.
