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 ;-)

Must have been a crap university - the University of Melbourne in
Australia had a computer on-site from 1956

http://en.wikipedia.org/wiki/CSIRAC

I used to take my punched cards over to CSIRAC in the Physics
Department in 1963. CSIRAC wasn't running then, and the punched cards
were taken from there to the university's IBM 7040/44 which was
located at the IBM office downtown at that time. The following year
the 7040/44 got shifted up to the university, and I eventually
qualified to operate it - I did most of my number crunching for my
Ph.D. project hands-on between 2.00am and 6.00am on that machine. The
electronic engineers kept the 11.00pm to 2.00am slot more or less
permantently booked.
