Requires: SmartSpice & Smartview

Minimum Versions: SMARTSPICE 3.16.12.R

The
input deck uses AC analysis and several sweeps in parameter values to see response in a simple circuit.
The results of the .MEASURE statement are stored in a separate output
file which is distinctly separate from the RAW file.

To run the simulation, Source the deck and press the green run button. When the simulation completes, the
results
are shown in SmartSpice log Window.
