Helmut: You have defined "AC 1" in two extra sources. This is simply wrong for
this application. Instead you should define AC 1 in the input source. By
the way it's bad practice to hide the AC-value in a V-sources as you
did.
A: it must be an accident. I ran your corrected "2stages_2CascodeDiff_ACsim_test2.asc"? and it works great, but I still don't see where are "AC 1" in two extra sources in my schematic. Could you please tell me where they are, so that I can learn from that.
Now slowly I understand what you tell me. I need time to think about what I learn so far from your guys and would like to go back to your guys for my full understanding.

Hello Hnguyen,

I have corrected your schematics and uploaded it into your folder. Simulate
with my files and you will see that everything is OK now.
