Transistor count ratio exceeds the theoretical information ratio.

Ternary implementations are more transistor-efficient overall.

Abstract

The MUX implementation of ternary half adders and full adders using predecessor and successor functions lead to the most efficient efficient implementation using the smallest transistor count. These designs are compared with the binary implementation of the corresponding half adders and full adders using the MUX technique or the typical complementary CMOS circuit style. The transistor count ratio between ternary and binary implementations is always greater than the information ratio ($log_2(3)/log_2(2)$ = 1.585) between ternary and binary wires.
