Abstract :
High electron mobility transistors (HEMTs)
have been shown to be high performance millimeter
wave devices due to their high-power gain and low noise
figures. From theoretical points of view presented the
noise behavior of HEMT. This work designs an
analytical noise model of an AlInN/GaN modulation
doped High Electron Mobility Transistor (HEMT). The
method used in the noise of high-frequency analysis is
designated and the different approximations commonly
used in the derivation of the noise parameter
expressions are discussed. The developed noise model
explains the performance of noise in both thermal noise
and flicker noise. The measurement techniques
providing the noise figure and the other noise
parameters are then described and compared. Small
signal parameters are obtained and used to calculate the
device’s Noise Figure (NF) simulate by using MATLAB
software.
