  A demonstration that e=2.718 rounded to 3 is the best radix for computation
is disproved. The MOSFET-like CNTFET technology is used to compare inverters,
Nand, adders, multipliers, D Flip-Flops and SRAM cells. The transistor count
ratio between ternary and binary circuits is generally greater than the
log(3)/log(2) information ratio. The only exceptions concern a circuit approach
that combines two circuit drawbacks (an additional power supply and a circuit
conflict between transistors) and only when it implements circuits based on the
ternary inverter. For arithmetic circuits such as adders and multipliers, the
ternary circuits are always outperformed by the binary ones using the same
technology.
