MOSIS Level 3 SPICE parameters do not include WD (lateral diffusion into the channel width). What value should I use for this parameter?
WD is not included in the MOSIS Level 3 model card in order to maintain compatibility with Berkeley SPICE. At the end of the NMOS and PMOS parameter lists, we include as comments delta W values determined elecrtically during parametric test. Use these numbers either to adjust the device widths in your netlist or to derive WD and add it to your model card, where WD is one half of delta W.
