Questions on TSMC 0.18um rf design kit

[wufeng]

Hi Guys,
I am new to TSMC 0.18um rf model. I am trying to simulate a LNF, but I met two problems.
1) The NMOS's width is 30 um. So I set the nr to be 12. But there is a worning message saying the minimum value is 16.
2) The inductanc needed is 0.7nH. But the minimum value is larger than this value.

Any comments or suggestions are welcome. Also does anyone have tutorial on the 0.18um RFIC layout with ads? Thanks!

Hi.
Selecting wider W, enable you to use lower number of fingures.:smile:
