Exploring Low-Power Implementation Techniques for 2:1 MUX Using Conventional and CNTFET Technology: a Performance Comparison

In this paper, implementation of 2:1 Multiplexer is done using two different technologies. Firstly, there is design of 2:1 MUX using Conventional techniques i.e. CMOS, PTL and TGL and secondly, 2:1 MUX is designed using Carbon Nano Tube Field Effect Transistor (CNTFET) based CMOS, PTL and TGL. Then, comparison of these two technologies is done based on Power Consumption, Delay and Power Delay Product (PDP). Simulation is done using HSPICE tool at 16nm technology node. After simulation, results showed that PDP is reduced by 98.38% for 2:1 MUX designed using CNTFET based CMOS, 99.75% for MUX designed using CNTFET based PTL and by 99.56% for CNTFET based TG as compared to conventional technologies. Here, least Power and PDP is shown by 2:1 MUX using CNTFET based PTL but least Delay is shown by CNTFET based CMOS. This proves that CNTFET technology has power to replace CMOS technology as its results showed better performance with respect to Power, Delay and PDP. From here, inference can be made that CNTFET is advanced and growing technology that can be used instead of CMOS for designing of low power electronic devices.
