If I have a bunch of diodes arranged in some complex, directed graph, can I get it to do computation?

I mean will it add voltages and, for example, as I insert voltage sources in-between the diodes? Can I implement a J/K flip-flop?


  • $\begingroup$ If you can implement an "AND" gate and a "NOT" gate then you can compute anything really $\endgroup$

  • $\begingroup$ (Given (resistors and non-controlled) voltage/power sources, you still need some characteristic curve with a significant section of negative slope.) There is Electrical Engineering@SE $\endgroup$

  • $\begingroup$ @nirshahar: I don't believe that will give you the capacity to do iteration or implemenet a stack. $\endgroup$

  • $\begingroup$ What model of computation are you working with? "Computqtion" can mean a lot of things, for example - one common model when dealing with circuits is this $\endgroup$

  • $\begingroup$ @nirshahar: That's a cool example. The model of computation is a simple Turing machine. $\endgroup$
