Noise Analysis of Sub Quarter Micrometer AlGaN/GaN Microwave Power HEMT
Tyagi, Rajesh K.,Ahlawat, Anil,Pandey, Manoj,Pandey, Sujata The Institute of Electronics and Information Engin 2009 Journal of semiconductor technology and science Vol.9 No.3
An analytical 2-dimensional model to explain the small signal and noise properties of an AlGaN/GaN modulation doped field effect transistor has been developed. The model is based on the solution of two-dimensional Poisson's equation. The developed model explains the influence of Noise in ohmic region (Johnson noise or Thermal noise) as well as in saturated region (spontaneous generation of dipole layers in the saturated region). Small signal parameters are obtained and are used to calculate the different noise parameters. All the results have been compared with the experimental data and show an excellent agreement and the validity of our model.
