Pico-second speeds in CMOS are power hogs... my usual design
cross-over point is around 250-300MHz.

In a WiFi repeater chip I come from 5GHz down to 250MHz in CML, then
CMOS.

Yes, but you went to school back when "circuit design" meant "circuit
design", not "simulating things you don't understand on software you
don't understand using a process you don't understand."

Yep.  I was educated 1958-1962 BC (before computers ;-)

I suppose that, for some people, being offensive is more important
than being right.

Actually, I was exaggerating. The first IBM all-transistor mainframe
was in place at MIT before 1960, the year I took summer courses in FAP
and Fortran... and there was a tube version before that.

I also used a DEC PDP-8 to compose my thesis.

It's what you learn, after you know it all, that counts.
