amplifier cadence simulation

Hi all,

I would like to ask how simulate the input current noise and the input voltage noise of an operationnal amplifier on CADENCE tool.
Exactally, what is the source which should make in the input of the amplifier ? It is possible to use an AC source and choose the noise simulation?

Thank you for all your efforts.

Can someone help me

please, I need your help
 

You should be able to creat a white noise for test purpose.
 

Hi Hajer,

Use the same setup as your .ac analysis for the
differential mode gain ... and just define your input
noise source as the source which you have connected
to your input devices. AC analysis gets executed
first and then noise analysis. You can see the output
noise and input referred noise from the direct plot
utility in ADE ...
