LTSpice IV - Operating Point - Newbie

Hi to all, I know, I'm a newbie and I'm prepairing the only electronics exam in my degree course in engineering. I have to solve this exercise:

**broken link removed**

and I want to get the operation point to know all the currents and tensions ... by this way I can check my calculations ... could you explain me how I can do this with ltspice IV?

.OP solves for node voltages and device currents at a single bias point.

.DC does the same as above while sweeping one or more sources.

Do you have a spice model for the specific FETs used in your circuit?

They are "normal" nmos transistors ... and I have these two models in spice:

I assume that the correct one is the first ...

Those are the generic ones that come with LTSpice; no guarantee that their parameters match the ones in your problem. The problem statement should have given some basic parameters for the FETs in the problem like Vt and Idss or gm. If those are provided, you will have to create or modify the LTSpice generic models to include those parameters.

Did I answer your question on how to use LTSpice to do the analysis?
