how to get the parameters of nmos in ads likes gm,Cox. THX!

1. Do a dc operating point simulation of a NMOS and PMOS with Vgs = 1V and Vds = 1.8V. (Or any other values of your choice.)
2. Find out Id and Vth of both transistors from the operating point
3. Use the equation Id = 0.5µnCox(W/L)(Vgs - Vth)2 and calculate µnCox
4. Try this out for different values of W/L, Vgs and Vds.
5. With more values you can also find out λ (Channel length modulation parameter).
6. If you are interested, you can plot the Id vs Vgs curve by doing a dc sweep. You can then use curve fitting techniques to find out what is the whether the square law holds true. I have seen that for L = 0.18µm, the equation has a power of 1.32.

There is a similar post here.

gm can also be found out from the dc operating point solution. I don't know how to get that in ADS though.
