How can I build a SR flip flop using op amps? (for a hand made 555 timer) Transistors may be used. I was thinking of using a hysteric op-amp and putting a schmitt trigger on the input of comparator 2. However, my solution fails in simulation. Here's my current circuit.
It works with the LTSpice model of a SR Flip-Flop so I know everything else is working as desired.
