Abstract(in English) Low-frequency noise characteristics of In_<0.52>Al_<0.48>As/In_<0.60>Ga_<0.40>As metamorphic high electron mobility transitors(MM-HEMTs) grown on a GaAs substrate are investigated. Dependence of low-frequency noise spectral density of the MM-HEMT having two 0.5x50 μm^2 gates on temperature(200K-400K)and gate and drain bias voltages is characterized for frequencies between 1 Hz to 53 kHz. The low-frequency input noise spectra of the MM-HEMT showed pure 1/f noise characteristics, indicating that there exist no deep trap effects for the temperature and the frequency ranges investigated. The MM-HEMT showed a very low noise spectral density(Hooge parameter: 3.7x10^<-5> frequency exponent: ~1.0)and a very small transconductance frequency dispersion(Δg_m/g_m<3%), which are comparable to the state-of-the-art InAlAs/InGaAs HEMTs grown on InP substrate. The results indicate a great potential of In_<0.52>Al_<0.48>As/In_<0.60>Ga_<0.40>As MM-HEMT grown on GaAs substrate for millimeter-wave circuit applications requiring low phase noise characteristics.
