Two interesting XOR circuits inside the Intel 386 processor

Not at all tired of the 386; an unrelated question comes up tho.

Have you done much on "high power" semiconductors yet?

It occurs to me that we're throwing around amps on ICs now that would've been well past "magic smoke" territory not all that long ago; perhaps you might find some ESC chips or something that demonstrate how this progress is being made?

I've looked at a few higher-power chips, such as the venerable 7805 voltage regulator, but I don't know if that's high-power enough for you :-) There's no high-power secret inside that chip except it uses large transistors.

Parent might be thinking of those Gallium-Nitride FETs that enable manufacturers to build suspiciously small power bricks.

I thought that was due to the higher switching frequency of the power transistors, perhaps unrelated to higher current draw in the transistor?
