that's what i call retro
Never heard it called that before.
has a wire from the (-) input to the output through a resistance
Yes it is used to control the hysteresis of the comparator.
I know it has no components, but I assemble it with real components and it doesn't work,
Yes that is why I was asking for the schematic of what you are trying to make with real components an part numbers to see if you had made a mistake with the conversion into a real circuit. There could be a problem with the type of op amp you are using, the feedback components or anything, but just saying it doesn't work is not very conducive to trying to find out what is wrong.
Basically it is a digital circuit but made with analogue blocks of that anadigm device. So you could just as easily do it in the digital domain.
I suspect however that you are not even getting a signal out of the first amplifier, do you have a scope you can measure things with?
