A Novel Quaternary Multiplexer using CNTFET

Multiple-valued logic (MVL) is a propositional calculus in which there are more than two truth values. In binary system due to difficulty in interconnection problems MVL preferred to solve and enhance in VLSI circuits. To work with MVL, Carbon Nano Tube Field-Effect Transistors (CNTFET) will be used. Quaternary multiplexer is one of the important circuit to be used in the design quaternary arithmetic and logic circuits. In this paper, the quaternary 4:1 Multiplexer designed using pass transistor logic to reduce the number of transistors. The proposed quaternary multiplexer design simulated using cadence Spectre with a CNTFET technology of 32-nm. The performance of these proposed design is tested for different parameters including power, delay and power delay product, with various supply voltages. The simulation results confirmed that the proposed quaternary multiplexer is better than existing one.
