This paper shows a practical approach to GaN-based HEMT self-consistent electro-thermal simulation for circuit modeling and reliability estimation. A physical-level lumped element dynamic thermal network able to describe the two-dimensional device geometry is self-consistently coupled with an electro-thermal compact large-signal model. The results obtained with the lumped-element thermal network are compared with finite-element simulations and shown to provide valuable estimates of the thermal… CONTINUE READING
