Nice BUT. The actual frequency/clock rate of a system is NOT defined by the transistor Ft value - it defined by the parasitics of the circuit it's placed into.

Nice BUT. The actual frequency/clock rate of a system is NOT defined by the transistor Ft value - it defined by the parasitics of the circuit it's placed into. If you build an IC with something like this, the claimed Ft does NOT define or allow the building of something far beyond the frequency or clock of what we have now. That is the fundamental flaw of both the PR by groups announcing such things and of non-EEs reading about them.
