The measurements of forward current-voltage characteristic and forward capacitance-voltage characte- ristic are ＇the most important methods to study the forward electricity characteristic of light-emitting diodes. Forward ahemating current （ac） small signal method can be used to measure the capacitance-voltage characteristic of light-emitting diodes, and negative capacitance can be observed. By analyzing the responds of light-emitting diodes junction capacitance by the alternating current small signalmethod based on forward direct current, w...
