Hi Ian,
First, I want to thank you (and your group) for all of your work on creating better MOSFET models in the linear area. That definitely improves my confidence in a new circuit I am designing through simulation.
Referring to the summary of models on page 14, post 274 of this thread, I believe there may be a couple of typo errors that crept in. The first one I noticed was for the IRF9610h. It returned an Unrecognized parameter "r-d" error. The threshold voltage was also approximately a +3.6 volts. By comparing the the other models, I came to the conclusion the "R-d" should read "Rd" and "Vto=+3.76" should read "Vto=-3.76". Making these changes in the model returned a reasonable Id(M1) simulation when a DC sweep from -10V to +10V was applied to the gate. I did not find similar errors on any of the other Pchan models.
Then I thought to check the Nchan models for similar typos. I did find three models (DN 2530, DN 2540 and LND150) which had "-" Vto values where as all of the other Nchan models had "+" Vto values. I have not tested any of these in a simulation, but thought it may be worth while for you to review these models also.
Again, than you for the hard work.
