【Abstract】 An optimizing parameter extraction technique and emulation software for high electron-mobility transistor (HEMT) small-signal model is described. Firstly, HEMT’s small-signal equivalent circuit is introduced, determining intrinsic and extrinsic elements. Secondly, a multibias decomposition-based optimization method is presented. Lastly, robustness and accuracy tests , using a different set of random starting values , are performed on measured-parameters of HEMT device. 更多还原
