I previously published a ΣΔ ADC circuit
https://everycircuit.com/circuit/4549196269223936,
but at that time i got the principal wrong. This time though, I'm quit confident, that I got it right.
The relays are obviously not part of the real thing, but they were necessary to get the simulation started.
Please note, that it takes a couple of samples after start or change of the input, before the result is accurate. And when i say accurate, I mean within a couple of decimals ;)
One sample is a full count to 50 on the most left displays, at which point the result is loaded to the displays to the most right. The middle displays show the sum of 1s in the bit stream. This counting is actually how it is done in reality at incredible speed.
