Comprehensive survey of ternary full adders: Statistics, corrections, and assessments

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