My notes don’t include what triggered the thought, but I think it was something in one of the Lee Smolin books I read recently. My recent post, Analog Computing, brought the idea to mind again, because analog computers often use op amps. I was reminded yet again while reading about SPADs.
I’m talking about the very useful rules of thumb (heuristics) I learned to help understand, even design, electronic circuitry. They’re shortcuts in the sense of being only approximately true, but their simplified view can make a circuit much easier to understand.
I thought I’d pass them on for those interested in electronic design.
Last fall I kicked off a series of math-y posts with 
If it hasn’t been apparent, I’ve been giving a bit of a fall semester in some computer science basics. If it seems complicated, well, the truth is all we’ve done is peek in some windows. From a safe distance. And most of the blinds were down.
The computer what? Connectome. The computer’s wiring diagram. The road map of how all the parts are connected.
