Hello,
I am fighting against an amp/comp in a 555 emulation, where the output is very instable (50mhz it appears). At least I suspect this is where the problem is.
It's happening only for the low comparator ; so I figured maybe it needs some hysterisis but I must admit it is kind of above my pay grade :-)
If someone has a solution or some ideas (the aim of this small project is to view step by step what is happening inside a 555 - probably someone already did it before).
