Small-signal modeling approach to 0.1-μm metamorphic HEMTs for W-band coplanar MMIC amplifier design
Publikováno v:
Current Applied Physics. 12:81-88
We present an accurate and reliable modeling method for designing the W-band (75–110 GHz) small-signal millimeter-wave monolithic integrated circuit (MMIC) amplifiers with the GaAs-based 0.1-μm metamorphic high electron-mobility transistors (MHEMT

We investigate the effects of a multigate-feeding structure on the gate resistance (Rg) and RF characteristics of the high electron-mobility transistors (HEMTs). In this structure, the increase of Rg with the gatewidth (W) is minimized; therefore, hi

We investigate the effects of the number of gate fingers (N) and gate width (W) on the high-frequency characteristics of 0.1 µm depletion-mode metamorphic high-electron-mobility transistors (MHEMTs). The extracted gate-to-source capacitance (Cgs), g
