A Novel Carbon Nanotube Field Effect Transistor based Arithmetic Computing Circuit for Low-power Analog Signal Processing Application

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.
