Plot NFmin vs IDS bias condition

[dtzounakos]

Hi.
Does anyone know how to plot NFmin vs IDS bias in Cadence?

Or does anyone know the exactly mathematical formula of NFmin?

My circuit is a MOS LNA with inductive source degeneration.

Thanks!

NFmin should be provided from the manufacture, can't be deducted from the S para.
Gamma Opt and Rn are also.

If you have a valid nonlinear model, you can obtain NFmin vs. IDS by doing Noise analysis.Because nonlinear models have-generally-noise elements.
NFmin is a function in the calculator-as I remember- in ADE of Cadence.You can use this function to plot NFmin vs. IDS..
