An incremental model of a solid state device is one which represents the
ac property of the device at desired operating point
dc property of the device at all operating points
complete ac and dc behaviour at all operating points
ac property of the device at all operating points

AC analysis describes the small-signal ac behaviour rather than the total DC behaviour. It linearises the non-linear device characteristics for small-signal analysis, focusing on how incremental changes in input affect output.

The analysis ranges from incremental input/output changes within the 'amplifier operation' region for any transistor.
