DC analysis provides for plotting static DC variables.
You can use DC analysis for various plots, including
transfer functions, where one source is varied, and
device IV curves, where two sources are varied.
Transfer function plots help to determine DC offset,
bias, and overall amplifier gain.
Numerous variables can be varied in DC analysis.
Among these are voltage and current sources, temperature,
and model parameters. The variables can be swept in
a linear or log method, or swept through a list of values.
