Shivani, 1) Yes. 2) Look at the 3D surface of Idiff, as shown in fig. 4.16 on pg. 36 in the IBIS cookbook http://www.eda.org/ibis/cookbook/cookbook-v4.pdf. If the surface is flat, i.e. its edges are straight you have a linear (resistive) differential current. (It doesn’t have to be horizontal, but it should not have a curvature to it in any direction). In this case you can use [R Series]. If there is a curvature in one or two directions, you will need to use [Series Current] or [Series MOSFET]. We do not model reactive characteristics with I-V curves, so L and C doesn’t come into this picture. 3) Vds is the voltage between the non-inverting and inverting terminals of the buffer. Look at pg. 51 in the IBIS Cookbook to see the explanation for Vtable. 4) Sorry, I do not have an example for you. I hope this helps.
