随着CMOS技术接近其极限，有必要探索电路在新的新兴技术中的应用，以使其快速商业化。碳纳米管场效应晶体管(CNFET)是未来用于低功耗、低电压数字或模拟电路的电子器件的理想候选者。本文针对低功耗模拟信号处理应用，提出了一种基于低功耗、低电压CNFET运算放大器(OPAMP)的模拟算术运算电路，包括反相放大器、同相放大器、加法器、减法器、微分器和积分器。利用HSPICE软件对所提出的计算电路在0.9V输入电源电压下进行了电路仿真。仿真结果表明，所提出的运算电路具有功耗低、运算速度快等优点，非常适合低功耗、低电压的模拟信号处理应用。
There is a need to explore circuit application in new emerging technologies for their rapid commercialization as the CMOS technology is approaching its limits. Carbon Nanotube Field-Effect Transistor (CNFET) is a promising candidate for future electronic devices for low-power low-voltage digital or analog circuit application. In this paper, we presented a low-power, low- voltage CNFET operational amplifier (OPAMP) based analog arithmetic computing circuit such as inverting amplifier, non- inverting amplifier, summer, substractor, differentiator, and integrator for low-power analog signal processing application. The proposed computing circuits operation are studied by using HSPICE software for circuit simulation at 0.9 V input supply voltage. Simulation results show that the proposed computing circuits well suited for low-power low-voltage analog signal processing application for their lower power consumption, and high speed operation.
