@ -230,12 +230,14 @@ switching from +V to -V to +V to -V ...
so now we've got our primitive logic gates.
we should be able to assemble them into something greater.
a good thing to build first would be an inverter chain (maybe even loop it back onto itself to build a ring oscillator).
a good thing to build first would be an inverter chain.
just take our clocked inverter, build 3 of these, and wire them in series, right?
TODO: 3-length inverter chain.
![](inverter-chain-naive.svg)
not that simple: we have a few stray signals we need to look closer at first (this is the part where i said "i'll address this later").
(i'm using the 3-wire inverter just discussed, where SET/CLEAR are folded into one CTL wire).
but it's not that simple: we have a few stray signals we need to look closer at first.
TODO: show why this doesn't work.
