Using the simulation models of the NMOS and PMOS
devices for the MCP43XX analog switch
we plot the device resistance when the devices are
turned on.

devices (R
voltage for the NMOS ad PMOS devices, the
resistance becomes very large (Giga s). In the
transistors active region, the resistance is much lower.
For these graphs, the resistances are on different
scales.

region and the resulting wiper resistance. For these
graphs, all resistances are on the same scale.
