under
DC
Bias
Sweep
In
this example
,
you
learned
how
to
evaluate
the
capacitance
characteristics
of
a
varactor
diode
under DC
voltage
bias
conditions
using
the
list
sweep
function.
Other
possible
applications
of the list sweep function include evaluating the capacitance of a capacitor under
DC voltage bias conditions and evaluating the characteristics of a coil
under DC current bias
conditions.
