Typically there would be no change, but different architectures will
have different responses. Many will have a tiny bit of hysteresis, some
will have a linear range. Others will oscillate. It's up to the designer
to insure the comparator works predictably, and that usually means you
will add positive feedback to get a calculated amount of hysteresis.
