In this chapter, we introduce small-signal modeling and parameter extraction technique for FETs, an III-V compound semiconductor device pseudomorphic high electron-mobility transistor (PHEMT) is used as an example. The parameter extraction includes pad capacitances, extrinsic inductances, extrinsic resistances, and intrinsic elements extractions.
