alt Hacker NewsIt's not complicated. It's just very basic capacitor behavior. If there is a tricky part here then it is in the bit that is glossed over: the switches. But congrats on getting it! Analog is fun, you can get incredibly complex behavior out of a handful of components.

All circuits are just very basic circuit element behavior. In fact a charge pump is a decidedly counter-intuitive thing, up there with things like "why a long-tailed pair makes a differential amplifier" or "how tf does a buck/boost regulator work?".
This is like looking at a 30-line function implementing a FFT and announcing "it's just very basic C code".

I was trying to figure out where the cursed part comes into it; I assume it's the switching, that typical circuit analysis just doesn't involve discrete states that are swapped between?
