A Novel Carbon Nanotube Field Effect Transistor Based Analog Signal Processing Circuits for Low-power Communication Systems

摘要

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 signal processing circuits such as Half-wave rectifier, Full-wave rectifier, Clamper, Clipper, Comparator and Peak detector for a low-power communications system design application. The proposed signal processing circuits operation are studied by using HSPICE software for circuit simulation at 0.9 V input supply voltage. Simulation results show that the proposed signal processing circuits well suited for low-power low-voltage communication application for their lower power consumption, high speed operation and high frequency response.
