Abstract :
The fan-in and fan-out limitations imposed by specific gate circuits force corresponding limits-upon the sizes of carry lookahead circuits fabricated from those gates. The relationships between those limits are derived, providing simple formulae that can be used by designers seeking to fabricate fast combinational binary adders.
