Any pointer ? Design tricks, theoretical analyses, synthesis methodologies: everything is welcome ! I am especially interested in CMOS, by the way... Thanks !

I am especially interested in CMOS, by the >way... What about Asynchronous CMOS design? Martin at Cal Tech, Ginosar at Technion, and I have all built CMOS circuits using Async design instead of clocked. My results seem to agree with thiers, in that the circuits run over a wide voltage range. Mine run between 0.70 volts and 5.5 volts (as high as my tester goes). Of course, there is a greater than 10x performance difference. Still, at less than 1.0 volts, they aren't using much power. Tom

I don't know any papers, but I remember at least two semiconductor manufacturers in Japan (and probably some in the U.S.) sell microprocessors which can operate at 1~2 V. These chips must have been developed using an ordinary CMOS technology. Difficult part may be I/O, and not use dynamic circuits, and change Vth. Sorry, company's name escapes me.
