Designing a Novel Ternary Multiplier Using CNTFET

Abstract

Abstract-Today, multipliers are included as substantial keys of many systems with high efficiency such as FIR filters, microprocessors and processors of digital signals. The efficiency of the systems are mainly evaluated by their multipliers capability since multipliers are generally the slowest components of a system while occupying the most space.Multiple Valued Logic reduces the number of the required operations to implement a function and decreases the chip surface. Carbon Nanotube Field Effect Transistors (CNTFET) are considered as good substitutes for Silicon Transistors (MOSFET). Combining the abilities of Carbon Nanotubes Transistors with the advantages of Multiple Valued can provide a unique design which has a higher speed and less complexity.In this paper, a new multiplier is presented by nanotechnology using a ternary logic that improves the consuming power, raises the speed and decreased the chip surface as well.The presented design is simulated using CNTFET of Stanford University and HSPICE software, and the results are compared with other instances.Index Terms-CNTFET, Multi-valued logic (MVL), Multiplier, ternary logic, carbon nanotube.

Ternary Logic Circuits Using Cntfet: A Brief Review

“…In (Azimi et al, 2014) ternary multiplier circuit is proposed with analog multiplier so as to reduce the circuit size .Ternary inputs are converted to analog inputs by using transformer , after generation of product by analog multiplier this analog product is again converted to ternary output by using analog to ternanry converter circuit.In the input side two ternary to analog converters are used. This multiplier circuit used as core multiplier is proposed in (Valle et al, 2001).…”

CNTFET-Based Ternary Multiply-and-Accumulate Unit

“…The multiplier is considered the most complex component in the ALU. Therefore, researchers are seeking to achieve the criteria of high speed, low cost, and reduction of the chip area by designing better multipliers [20].…”
