“…The emerging new generation of transistors such as CNTFET (Carbon Nano Tube Field Effect Transistor), has helped in overcoming some limitations of CMOS technology. Therefore, many of these full adders are designed using this new technology [8][9][10][11][12][13]. CNTFET transistors have better performance compared to CMOS transistors.…”

This paper presents a new low power and high speed full adder based on Carbon Nano Tube Field Effect Transistor (CNTFET) technology. This proposed full adder is based on a XOR logic function using 32 nm CNTFET technology. The MOSFET-like CNTFET is applied in this paper to use CMOS (Complementary Metal Oxide Semiconductor) logic gate. The better structure of CNTFET transistors can improve the performance of full adder based on CNTFET technology [1]. The proposed full adder is simulated in different frequencies, various supply voltages, temperatures and load capacitances to prove better performance in different conditions using the Synopsys HSPICE simulator software in comparison with previous full adders in CNTFET technology.

Dynamic logic is a well-known logic style which is widely used in digital electronics. A mixed dynamic/static full adder cell is presented in this paper with the aim of reaching high efficiency. The midoutputs are obtained from a Multi-output dynamic module. Then, a multiplexer generates final outputs in the static part. Several conventional and state-of-the-art dynamic adders are also surveyed and compared in the paper. All circuits are simulated by HSPICE with 32 nm CNFET technology. The proposed design is the fastest dynamic adder cell. In addition, it has approximately 5% higher efficiency in terms of PDP than the second most high-performance cell, which is DDCVS.

“…[1][2][3][4][5][6] Since integrated circuits in Metal Oxide Semiconductor Field Effect Transistors (MOSFET) technology keep to scale down into nanometer limited areas, this art is starting to face various troublous challenges. Several of these challenges are: intensive process variations, decreased gate control, increased short-channel effects, and exponentially rising leakage currents.…”

This paper presents a high speed design of 4-to-2 compressor, using Carbon Nanotube Field Effect Transistor (CNFET). CNFET is very suitable for low-voltage and high-frequency applications. Several conventional and state-of-the-art 4-to-2 compressor cells are also surveyed and compared in this paper. All designs are simulated by HSPICE with 32 nm CNFET technology. These designs have also been simulated at different supply voltage and different frequencies, load capacitors, and temperatures. The simulation results confirm that the proposed design is the fastest 4-to-2 compressor in different working circumstance.
