It's true that most FPGAs have limited built-in analog capabilities. But good DACs and ADCs aren't too expensive, and an FPGA can control them with exceptional precision. Does your process have some kind of input / output that can't be handled that way?
Dedicated DACs/ADCs will almost always offer better performance than the ones you'd find on a microcontroller or even an ASIC.
- koeng 2y agoYou don't even need DACs or ADCs, you just need an SRAM cell leaking current through an electrode. The process is entirely separate from that. By analog, I don't mean the signal, I mean the chip is interacting with the world physically. I need the electrodes physically touching chemicals. Those chemicals are incompatible with the aluminum or other normal metals on those connections - you pretty much need platinum or the metal from the chip will screw up the chemical reaction. You also need large amount of input/output - a good start on a chip would be about 1,000 to 10,000 electrodes. I think it is going to be difficult to put that many on an FPGA.
