I am designing a CMOS comparator with hysteresis. I had a basic question. What is the difference between a Schmitt trigger circuit and a comparator with hysteresis? Are they the same? Could someone please help me out?
Also how do I decide on an architecture for a comparator with hysteresis?
lets get clearity:
Comparator compairs two signals voltage /curent and gives logical output. no built in hysteresis, can be added by feedback elements. refrence is still available.
Schmitt trigger : has inbuilt hyterisis , the refrence is set inside by design.
finally opamp can be used as comparator, but not vis-a-versa. design an op-amp and use it like comarator is sign of bad designer.
