hysterisis comparator

Pls reference following sch:
 

the technique is simple in CMOS IC design:
hyeterisis can be done in both side of the reference, or one side of
the reference.
double side :
generate a current path that will activated whenever output is "1" or "0" to the other input of the comparator.
one side :
( +hysterisis ): whenever output is "1"/"0", generating a current added
to "-" input of the comparator
(- hysterisis ) : whenever output is "1"/"0", generating a current
subtracted to "-" input of the comparator

I think using positive feed back would be better in this application( Schmit Trigger)
 

This is single supply hysteresis op. amp. which I use very offen.

Good thing is that this op. amp. has big input resistance.

Best regards.
