Sensitivity Analysis
Sensitivity analysis calculates the small-signal DC sensitivity of one or more output expressions to one or more input variables. Sensitivity is defined as: Change in an output expression / Small change in an input variable The "Small change" part is important, as the intention is to approximate the value of the derivative at the nominal operating point. Sensitivity analysis is like transfer function analysis, except that it calculates the sensitivity of almost any DC expression to any variable that can be stepped.
