I'm trying to make a circuit that will detect a sudden positive change in input voltage. The idea behind the attached design is that if the input voltage (which is mostly DC) increases suddenly, the non-inverting input on the comparator will momentarily be higher than the non-inverting. However, when I implement this, the output is always high. I'm guessing this has something to do with the fact that there is a path between my inverting and non-inverting inputs, but I wanted another opinion.
Any ideas why this isn't working? Am I even close?
I am using a LM311N as my comparator.
