Can someone let me know how this circuit works?


Clue:  hysteresis

Context..errmm.. This was designed by Alan Tyger. and its called Flip-Flop Memory Op-amp.

The op-amp has a positive feed back and I know that it has something to do with hysteresis..I tried to understand, but just cant figure out how this works..

It's an RS latch (without a complementary output.)  http://cs.fit.edu/~wds/classes/comp-org/Logic/sequential.pdf
I don't know who Alan Tyger is, but that circuit is as old as the hills.
It'd be better to use a dedicated comparator.  A comparator can be made from an opamp, but a comparator (LM339) is better suited to the task.
