The graph for this test plots 590 capacitance (red trace) and 595 quasistatic capacitance (blue trace)
versus bias voltage. The figure below shows a typical graph that is generated by this test.
The shape of the curves in the following figure indicate that measurements were made with the
device in equilibrium. If the curves for your test deviate significantly, the device was probably not in
equilibrium. Do the equilibrium test (
QTsweep82
) to determine the optimum delay time (
Delay595
parameter) to use for the
simcv
test (
SIMCVsweep82
user module).
