A hysteretic comparator will be difficult to get any good
unity gain bandwidth for. You can't put and keep it linear.
To measure hysteresis use a sine or triangle wave and
take the input and output cross() time -> voltage values,
and subtract lower trip-voltage from upper. Use a period
that is >> prop delay.
Comparators are analysed in term of "slew rate" instead of bandwidth.In order to do this, a transient simulation can be done.
Hysteresis is easy.. Apply a sine-wave and check the zero crossing time points when the signal drops down from threshold level.The difference between two points will give you hysteresis.
