Noise Summary

Do anyone know what's the meaning of "fn" and "id", which is related to the noise of MOSFET (model used: bsim3v3)?

I have thinking that probably "fn" is the flicker noise and "id" is the thermal noise components. But I don't think there is so much flicker noise in the design (it is an ADC, the sampling rate is at 40 MHz). I think another explanation is "fn" = thermal noise and "id" = shot noise. Do any one have any ideas? Thanks in advance!
 

Re: Noise Summary

If you are using the BSIM3 models it can not have the Shot Noise analysis in its noise model and use only Thermal and Flicker noise analysis models and rest of the noise is ignored.
