High-Performance 4 x 1 Multiplexer based on Single-Walled Carbon Nanotube Field Effect Transistor with CMOS-like Pass-Transistor Logic

In the current research, the best property of Carbon Nanotube Field Effect Transistors (CNTFETs) exploited to propose a high performance 4-input 1-output (4 x 1) Multiplexer, using a CMOS-like Pass Transistor Logic (PTL) design style. To enhance a significant reduction in circuit complexity and a corresponding improvement in the performance envelope (power, area and speed) with respect to conventional CMOS equivalent circuit. The operating principles and experimental results for the PTL circuits using both p-FET and n-FET of CNTFETs presented. This property can be used in a multiplexer circuit, which transfers one of several input data to the output according to the control signal values. Results demonstrated that using of CNTFET can be achieved by constructing high performance carbon nanotube-based integrated circuits like logic Multiplexer based on a pass-transistor logic configuration. Further, this circuits can assembly with other circuits based on other Field effect transistors technology like GNR-FETs and improve ALU (Arithmetic Logic Unit) section of many processor ICs in high level of Nano-Scale VLSIs. The simulation results presented, and the power consumption compared with the conventional CMOS designs. The comparison of results approved that the CNTFET based design is capable of efficient power savings and high-speed performance.
