haha... self timed domino .. published like 10-15 years ago already.<p>this won't work for many reasons that everyone in the industry already knows. High fan-out back to many gates that are spatially distant means that you need not only complex routing, but also complex sizing of the feedback inverter. So.. this won't even fit in with automatic place and route of complex cells. And good luck doing this custom in an efficient way such as making it a semi standard cell library.<p>Furthermore, the feedback inverter only works in simple cases such as the cascaded gates you show, when the switching of the one gate depends only on one fan-out. If it depends on more than one fan-out, the feedback inverter essentially requires another logic gate in front of it, which simply just blew up your entire circuit size and any power savings you were attempting.
This is just NULL-Convention Logic, renamed so they could trademark it. I mentioned NCL in a comment under the micropipelines <a href="https://news.ycombinator.com/item?id=11425533" rel="nofollow">https://news.ycombinator.com/item?id=11425533</a>
