摘　　要：针对三值比较器速度慢和功耗高的问题.在研究多值逻辑电路工作原理和比较器电路结构的基础上,提出一种碳纳米场效应晶体管的新型多位三值比较器.该电路首先将三值译码信号输入到比较器中,然后对比较结果进行编码转换,最后将各个模块组合为多位三值比较器.实验结果证明其具有正确的逻辑功能,较快的速度和低功耗特性.As the ternary comparator faces problems of slow speed and high power consumption, this paper proposes a scheme for the magnitude ternary comparator of CNFET, which is researching on theory of multi- valued logic circuit and the structure of comparator circuit. First, the ternary decode signal is propagated to the comparator, then the encoder circuit encodes the results of comparison, and finally the magnitude ternary comparator is made up of all kinds of modules. The magnitude comparator is simulated by software, which demonstrates that it has a correct logic function, fast speed and low power consumption characteristics.
