Abstract:

 

Carbon nanotube field-effect transistors (CNFETs) utilize   an array of carbon nanotubes as the channel material instead of bulk silicon   in the traditional MOSFET structure, which holds great promise for the   future of integrated circuits. In this paper, a full adder cell based on a   parallel design using CNFETs is presented. The main objective of designing   this full adder cell is to reduce critical path delay in CNFET-based adder   circuits. The proposed design positively affects speed and power consumption   by shortening the data path. In order to evaluate the proposed design,   several simulations were performed with different load capacitors,   frequencies, and temperatures using HSPICE in 32-nm CMOS and 32-nm CNFET   technologies. The proposed full adder cells were compared with five other   full adder cells using 4-bit ripple carry adder (RCA) and 8-bit RCA circuits   with power consumption, speed, and power delay product parameters. The   obtained results indicate that the proposed design is faster than other   designs due to a shortened data path. The results of the simulations confirm   the higher efficiency of the proposed full adder cell with respect to other   designs.
