Need these papers on transistor noise,pls help me!

Hi all,

I can't download these papers from the IEEE. so pls help me find them.

1) H.Statz, H.Haus, and R.Pucel, Noise Characteristics of Gallium Arsenide Field-Effect Transistors, IEEE Transactions on Electron Devices.

2) A.Podell, A Functional GaAs FET Noise Model, IEEE Transactions on Electron Devices.

And are there some papers on BJT transistor noise model and characteristics analysis? if there are, pls help me download them together!

Thanks a lot!

Maybe this publication will bo of any use to you:
"Noise Modeling for Semiconductors"

Thank you, IanP.

It is helpful but I want to get the formula expressions of BJT noise characteristics.
