input and output noise simulation with Spectre Noise analysis?

isazulkc
Hi, I would like to know if the output noise (V-rms) obtained when I simulate the output noise of a circuit with Spectre simulator (Noise) include the noise of ALL the components referred to the output ? In fact I got some inconsistant result when comparing the input and output noise (V-rms) given by the simulator. I got 1.4 mV-rms at the output while I have 13 mV-rms as input refered noise. I know input referred noise give the input equivalent noise (anasimhelp) considering a noise-free circuit, but I am note sure for the output noise. Thanks for your help!! Best regards

     hi Andrew,

     i did ended up running pss and pnoise on the circuit and was able to retrieve the individual device noise. thanks Andrew
