“…CNTs have appropriate features such as ballistic convey of electrons along the tube and a simple construction process. These features make them appropriate for designing CNFETs [17]. CNTs are classified into two categories: single-wall CNTs (SWCNTs) and multi-wall CNTs (MWCNTs).…”

“…CNTs are classified into two categories: single-wall CNTs (SWCNTs) and multi-wall CNTs (MWCNTs). SWCNTs are composed of one cylinder while MWCNTs have more than one cylinder [17]. Each CNT has a specified vector called chirality, which is defined as 12 ch = na + ma : where, (n, m) are chiral numbers and (a 1 , a 2 ) are unit vectors [11].…”

“…One of the most advantageous features of a CNFET device is that the appetence threshold voltage can be adjusted by adopting appropriate diameter for its CNTs [17]. This feasible characteristic makes CNFET more flexible than MOSFET for designing digital circuits and makes it very appropriate for designing multi-threshold circuits [5].The threshold voltage of CNFET is computed by (2) [17]. …”

Abstract-In this paper, a new high-speed and energy efficient 4-to-2 compressor cell was presented using carbon nanotube field effect transistors (CNFETs). CNFET is very suitable for high-frequency and lowvoltage applications. In addition, in this paper several conventional and state-of-the-art 4-to-2 compressor cells are surveyed and compared. In order to evaluate the proposed designs, computer simulations are carried out using 32nm-CMOS and 32nm-CNFET technologies. Simulations are conducted using various low voltage power supplies, different temperatures, frequencies and load capacitors. Results of simulation demonstrate predominance of the proposed design in terms of power consumption, delay, and power-delay product (PDP) compared to other 4-to-2 compressor cells and they confirm that the proposed design is the fastest 4-to-2 compressor in various working circumstances.
