A simple charge-control model for light-emitting diodes exists. The equation may be applied to both waveform analysis and synthesis (current preshaping). At high current levels, the cutoff frequencies are higher than predicted from the static high-injection lifetimes alone. The harmonic contents in the output may be frequency dependent at high current levels and cannot be completely determined from die static intensity-current curve.
