摘要

本文介绍了一种基于碳纳米管场效应晶体管(CNFET)的超快速比较器,并给出了该比较器主要性能参数的仿真结果。由于CNFET器件被广泛认为比CMOS器件快得多,因此CNFET比较器的性能应该比CMOS器件高得多。因此,从仿真结果分析了CNFET比较器的上升和下降延迟、增益、平均功耗等瞬态响应的关键性能,并与相同条件下CMOS比较器的仿真结果进行了比较。采用0.5μm CMOS工艺模型和HSpice CNFET器件模型,在HSpice平台上对两种比较器进行了仿真。

Design and Performance Analysis of Ultra Fast CNFET Comparator and CMOS Implementation Comparison
This paper presents an ultra fast comparator using Carbon Nanotube Field Effect Transistor (CNFET) and the simulation results of prime performance parameters of this proposed CNFET comparator. As CNFET devices are widely considered much faster than their CMOS counterparts, the CNFET comparator should show much improved performance than the CMOS one. Therefore the key performances of the comparator like rising and falling delay, gain, average power dissipation and other transient responses of the proposed CNFET comparator are analyzed from simulation results and are compared with the simulation results of the CMOS comparator in the same condition. Both the comparators are simulated in HSpice platform by using 0.5μm CMOS process model for CMOS comparator and HSpice model of CNFET devices for CNFET comparator.
