Abstract: Carbon Nanotube Field Effect Transistor (CNFET) is a promising new technology that overcomes several limitations of traditional silicon integrated circuit technology. In recent years, the potential of CNFET for analog circuit applications has been explored. This paper proposes a novel four quadrant analog multiplier design using CNFETs. The simulation based on CNFET technology shows that the proposed multiplier has better features than CMOS Multiplier. Multiplier-divider circuits is using in digital signal processing base on neural networks and communications (amplifiers with variable gain, modulators, detectors and,…).In Most of CMOS analog circuit, transistors are only in triode or saturate regions; till now both regions not used. In this one kind of current mode multiplier- divider circuits is intrudused.it is very simple, has low die area and wide range in low voltage . all tough this circuit has no sense to temperature variation and varying parameters.
