Hi
I am designing a W Band LNA. I have already made the schematic diagram in ADS and I am getting the results that i wanted.
My supervisor told me that in HARMONIC BALANCE simulation , there is an option or tool which we can use to see how much noise each component is adding in the overall circuit. I have tried to find it for a whole week now but I could not find it.

Can someone please guide me in the right direction as how can i find the noise contribution of each component in my overall schematic diagram.
I have made a two stage Casocode Amplifier. If you require any further information please let me know. I will share it at once.

Any sort of help will be greatly appreciated. Thank you
 

There is a tab in s-parameters controller called as "Noise". You have to activate Noise and Noise Contributors under this tab.
By this way, you will able to see noise contributors and their values.
 

Thank you so much for the reply. I got busy with the layout of my Amplifier Design . I just finished my layout and so i got back to this issue today. I have added two pictures below. One is for the S parameter controller. I wanted to show you the settings that i choose for it.
My ports are 1 and 2.
0.5dB is the threshold. It means that dont shows me the noise contributors which have less than 0.5dB in this case. I am confused about the bandwidth option even after reading the explanation in Help. So i just kept it like this.

Now when I simulated my circuit . I and i try to plot something, I don't know how to plot the noise contributors. I have attached a second picture below of the options that i get when i plot something. How can i identify the noise contributors . Can you please the identify the mistake that i am making. Thank you
