Nowadays, VLSI technology mainly focused on High-Speed Propagation and Low Power Consumption. Addition is an important arithmetic operation which plays a major role in digital application. Adder is act as an important role in the applications of signal processing, in memory access address generation and Arithmetic Logic Unit. When the number of transistors increases in system designs, makes to increase power and complexity of the circuit. One of the dominant factors is power reduction in low power VLSI technology and to overcome the power dissipation in the existing adder circuit, MTCMOS technique is used in the proposed adder. The design is simulated in 90nm, 70nm, 25nm and 18nm technology and then comparison is made between existing and proposed system in the context of energy, area and delay. In this comparison, the efficiency metrics power and delay are found to be reduced 20% from the existing adder and the proposed adder is used for the design of low power multiplier.
