Abstract:In this paper an improved Gray-Wolf-Optimization (GWO) based small-signal modeling is developed. The proposed method is demonstrated by modeling GaN High Electron Mobility Transistors (HEMTs) on SiC and Diamond substrates. The technique bases on engineering the optimization objective function to provide reliable values for the model parameters; while keeping a better fitting for the targeted measurements. The reliability of extraction has been further improved by using physical relevant condition to remove any… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
