Abstract: 
A lot of research has been done on multiple-valued logic (MVL) such as ternary logic in these years. MVL reduces the number of necessary operations and also decreases the chip area that would be used. Carbon nanotube field effect transistors (CNTFETs) are considered a viable alternative for silicon transistors (MOSFETs). Combining carbon nanotube transistors and MVL can produce a unique design that is faster and more flexible. In this paper, we design a new half adder and a new multiplier by nanotechnology using a ternary logic, which decreases the power consumption and chip surface and raises the speed. The presented design is simulated using CNTFET of Stanford University and HSPICE software, and the results are compared with those of other studies.

基于碳纳米管场效应管的新型三元半加器及乘法器

概要:多值逻辑(multiple-valued logic, MVL),例如三元逻辑,在近年来是大量研究项目的研究对象。MVL可以降低必要操作的数目、减小芯片面积。碳纳米管场效应管(CNTFETs)被认为是硅晶体管可行的替代方案。将CNTFETs与MVL结合,可以得到更快、更灵活的独特设计方案。本文利用微纳技术和三元逻辑设计出了新型的半加器和乘法器。微纳技术和三元逻辑的采纳降低了元件功耗和面积,提升了元件运行速度。我们利用斯坦福CNTFET模型和HSPICE软件对本文设计器件进行了仿真,并将仿真结果与相关研究结果进行了对比。
