If you implemented it
And how many depletion load resistors.?
Also true. A lot of the power estimates have been
based on the assumption that
we have bipolar transistors. What about discrete mosfets? We could do NMOS or
even CMOS designs directly that way...
MOSFETS solve half the problem. There are still load resistors on the
chip never minding all of the registers are constructed like DRAM IE: they
are capacitors. That dynamic logic and memeory is very hard to simulate
at tyhe discrete level. If you simulate them using static cells the
transistor count goes up a factor of 6 for each BIT of register plus a
lot of resistors that dynamic logic does not use.
