As researchers investigated for high-performance digital circuits for future generations, Carbon Nanotube Field Effect Transistors (CNTFETs) is considered as the most promising technology due to their excellent current driving capability and proved to be an alternative to conventional CMOS technology. A CNTFET based energy efficient ternary operators are proposed for scrambling applications. The transistor-level implementations of operators namely Scrambling Operator1 (SOP1), Scrambling Operator2 (SOP2) and SUM operators are simulated with CMOS and CNTFET in 32 nm technology at 0.9 V supply voltage using Synopsys HSPICE. The performance metrics like Power, Delay and Power-delay product (PDP) are measured and a comparative analysis for CNTFET and CMOS technologies is carried out. The results demonstrate that CNTFET designs have better-optimized results in power, energy consumption, and reduced transistor count.","PeriodicalId":268157,"journal":{"name":"Volume 4,Issue 5,2018","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133966436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first-order temperature coefficients for E12g and A1g modes are found to be -0.0133 cm-1K-1 and -0.0092 cm-1K-1, respectively. The physical origin of the non-linear temperature dependence is analyzed using an analytical model that includes contribution of the thermal expansion and an-harmonic effects to the lattice potential.
