Help me simulate the NFmin vs bias and design an LNA in ADS

I use ADS to simulat the NFmin vs bias
I am so stupid. I should plot NFmin vd Vbias and I-V curve
but i find someone can only plot NFmin vd Ibias
if someone have an idea, may u give me the ADS example

After i determine the bias and width, i use inductor etc. to match
but the nfmin is changed.why?
can anybody tell me how to design a LNA?
I need help,please give me the ADS example for LNA
Thank you

is it a CMOS LNA , or discrete LNA ?
u need to check gonzalez book and tom lee book
