PORTn.NC.vnc, nf(1), nf(2) in ADS?

Hi,

What does the data of PORTn.NC.vnc stand for in @DS SP simulation? input referred noise? output-referred noise? or something else?

Also, what does nf(1) and nf(2) stand for? little information can be found in the @DS document.

Thank you very much.

If possible, please also advice how to get the input referred noise / output-referred noise in @DS?

I found that PORTn.NC.vnc is the output referred noise, any comments?

thanks.

nf2 is the npise figure of your amd
