I'm trying to simulate the noise psd of nmos. but when i performed the noise analysis and plotted the resulting output noise, it is zero over all the frequency range? could someone help me? thanks.
 

Hi sarge,

Thanks for your helpful suggestion! I modified it and it works. the node of which I tested the noise voltage cannot be disturbed by noise since a constant ideal voltage is connected to it, right?

Hi,

Try to remove voltage source V1.
