lna design ads
i designed an LNA and drawn schematic now i need to simulate but as i am new to ADS i donno how to simulate ?.. it is showing error...
can anyone explain the steps i have to follow to simulate.. i am entirely blind to ADS..
pls help..
what is the frequency band ?
and what si the transistor
check this link

thank you for the info... really i need to know how to start the simulation in ADS...
hi my friend,
what kind of a simulation do u want to do?
best regards,
what kind of model do u use , sparamter file , or nonlinear model
tell me me , and soon i will send a detaled steps for simulation in ADS
khouly
nonlinear model
what is ur frequncy , and what is the transistor ur using

i think you should find an example in ads design training file.
then step by step you will get more.
which version of ADS u hv got?
There's a complete step-by-step tutorial on how to design & simulate a LNA using ADS at this site
http://www.odyseus.nildram.co.uk/RFIC_Circuits_Page.htm
Check on the LNA circuit.
check these ADS tutorials
http://www.wiss.ece.okstate.edu/reso...DS/ads_tut.htm
i think they might be useful
these are some good tutorials for LNA design step by step using ADS.It really helped for me
go to this post and download the 2 tutorials

ye....
I think those are good tutorial ,too
but ,how can i get the cmos14 0.5um process?
u can get a simple MOS model from MOSIS and convert it to ADS model

first try this site www.freescale.com to load down the ads model for your transistor like ATF54132. Then build the circuit in the schematic and smiluate the S parameter, noise, gain IP3,ect+. And make some modification to your circuit and simulate it again.There is a complete tutorial about amplifer in the example section of ADS.
also www.avagotech.com , have a loads of appnotes about how to design LNA using the BJT and pHEMTs they produce
