Help with Low-Noise-Amplifiers

[raghav]

I request u all 2 help me with links and uploads related to LNAs.








Pls hurry up its urgent.

You might need to look at manufacturer application notes. For example, **broken link removed**

It contains usful information on the device such as how to stabilize it.

Hi,

Following are the good documents on LNA design using RF CAD tool (Microwave Office)
1. 17GHz and 24GHz LNA Designs based on Extended S-parameter with Microstrip-on-Die
in 0.18µm Logic CMOS Technology paper (PDF) by Intel Research & Development

http://www.appwave.com/src/news/articles/AR0307.pdf

2.Broadband_RF_LNA.pdf

3. Designing a Low-Noise Amplifier with VoltaireLS (LNA_Appnote.pdf) by Maas
and
4. **broken link removed**
**broken link removed**
I hope this helps in LNA design & analysis

good luck

this is one of the most cited papers about LNA

sir,
i want to drsign cmos LNA using awr tool .In my circuit i hav each and every value.
i draw that same ckt in tool but i am not getting same results.
For s11,s22,s12 parameters i want nagative values but i am getting positive values.
for gain(s21),i want positiv value but i am gettng negative value.
plz send somae awr manual + cmos LNA design and i am sending my ieee paper also
plz help me..

sorry but how u know that transistor model is correct?

Hello Rizwan,

OKay no problem we can help to resolve these issues...

I went through the article & found the following, in order to construct MWO schematic...
What Type of CMOS device Model Parameters you used? (say BSIM model with exact parameters)
Or Do you use the S-parameter file of the CMOS Device model?
Or Do you use any specific Process Design Kit (PDK) CMOS model such as TOWERJAZZ? or TSMC?

Send / uplod your AWR MWO project file *.emp so that I will try to help you better...
