Hi guys, first post here. Kinda desperate here, as I've done so much reading and I've yet to figure it out.
I have to build an 8-bit ADC converter using successive approximation method. But the kicker here is that I do not have a strong background in electronics (And I haven't even taken digital electronics). Long story short I've been forced to take this class without having the necessary requirements. Anyway, as I said, 8bit SAR ADC. I've looked at countless block diagrams, and I know how to do the integrator and the comparator. A counter will be an IC, so that won't be an issue. But my issue is actually designing a full circuit for the thing. Excuse the somewhat silly question, but what is control logic and how does someone simulate it? I can't use an IC or microcontroller, the only ICs I'm allowed to use are for the op amp and the counter (and if I use DACs, which is not mandatory). Does anyone have a full circuit for it, and not a block diagram? It would help if I'd at least have something infront of me that I could build and then try to understand. Looking at SAR ADC IC datasheets, most use other ADC ICs, and as I said, that's not allowed for me. (i.e: https://www.electro-tech-online.com/custompdfs/2013/04/MAX11120-MAX11128.pdf )
