After the first white light-emitting diodes (WLEDs) became commercially available, much attention has been paid to the development of WLEDs because of their extensive applications in solid lighting. Compared with traditional lighting, WLEDs have more advantages, such as high efficiency, long lifetime, fast response and environmental-friendliness [1-3]. It has been widely used in signals, displays...
A charge based compact model with self-heating effects has been developed for LDMOS transistors. Both the channel and drift regions in LDMOS are modeled without adding an internal drain node. An efficient scheme for including self-heating effects is implemented in the model, which requires no thermal network. A comparison with measured data from an LDMOS shows that the model has excellent accuracy...
