Abstract: designing a mux for low power to use it as a repetitive block in the barrel shifter will considerably reduce the simulation time .our basic objective is to compare existing 2:1 multiplexers with proposed multiplexer design in term of power consumption, temperature sustainability, noise immunity and frequency, so that a fast and optimized barrel shifter can be designed by the help of it.a 2:1 multiplexer is a basic building block of the “switch logic”. The multiplexer circuit is typically used to combine two or more digital signals onto a single line, by placing them there at different times. Technically, this is known as time-division multiplexing. Multiplexers can also be used as programmable logic devices. By specifying the logic arrangement in the input signals, a custom logic circuit can be created. The selector inputs then act as the logic inputs. This is especially useful in situations when cost is a factor and for modularity. The increasing prominence of portable systems and need to limit power consumption has led to rapid and innovative developments in low power vlsi design during recent years. The driving forces behind these developments are portable device applications requiring low power consumption and high throughput due to their small chip size with large density of components, increased complexity and high frequencies.
