“…Moreover, they provide a kind of parallelism in the RCA scenario when the first THAs in each bit positions can perform simultaneous computations. This is one of the reasons why the RCA constructed by [17] is very fast. Once the ternary inputs are decoded, the employment of ternary gates is no longer needed, and binary gates can be replaced to improve performance. The TFA in ref.…”

“…Hence, for the sake of brevity, the next step is to remove TFAs whose structures are repetitive from our list. Our final selection from 11 papers [17,21,35,37,58,60,87,95,[101][102][103] forms a reasonable range of TFAs with various design methodologies and logic families. The elimination of TFAs at this stage is because of their similarity to the selected ones.…”

The history of ternary adders goes back to more than 6 decades ago. Since then, a multitude of ternary full adders (TFAs) have been presented in the literature. This article conducts a review of TFAs so that one can be familiar with the utilised design methodologies and their prevalence. Moreover, despite numerous TFAs, almost none of them are in their simplest form. A large number of transistors could have been eliminated by considering a partial TFA instead of a complete one. According to our investigation, only 28.6% of the previous designs are partial TFAs. Also, they could have been simplified even further by assuming a partial TFA with an output carry voltage of 0 V or V DD . This way, in a single-V DD design, voltage division inside the Carry generator part would have been eliminated and less power dissipated. As far as we have searched, there are only three partial TFAs with this favourable condition in the literature. Additionally, most of the simulation setups in the previous articles are not realistic enough. Therefore, the simulation results reported in these papers are neither comparable nor entirely valid. Therefore, the authors got motivated to conduct a survey, elaborate on this issue, and enhance some of the previous designs. Among 84 papers, 10 different TFAs (from 11 papers) are selected, simplified, and simulated in this article. Simulation results by HSPICE and 32 nm carbon nanotube FET technology reveal that the simplified partial TFAs outperform their original versions in terms of delay, power, and transistor count.
