RUN TIME DELAY COMPENSATION FOR A FLOATING DOWNWARDS LIGHT DIODE (LED) DRIVER

摘要

Devices, systems and methods for improving the current deviation of a light-emitting diode (LED). Some aspects include 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 is controlled by a gain selector coupled to the variable gain amplifier by changing the gain of the variable gain amplifier based on the on-time of a signal.
