In this paper, we present an improvement for LED driver circuit by inserting a threshold voltage on the resistive branch of the conventional RC current-shaping circuit. The proposed method enhances ...

Nonlinear signal distortions originated in a resonant-cavity light emitting diode (RC-LED) are investigated. Using laboratory measurements and offline processing, the RC-LED's nonlinear behavior is ...

With LED lighting becoming increasingly popular due to their high luminance, long life, high efficiency and decreasing costs, the subject of controlling and driving the LED's is now a very interesting ...
