Design and Implementation of 16-Bit Magnitude Comparator Using Efficient Low Power High Performance Full Adders

In VLSI applications, area, delay and power are the important factors which must be taken into account in the design of a fast adder. The paper attempts to examine the features of certain adder circuits which promise superior performance compared to existing circuits. The advantages of these circuits are low-power consumption, a high degree of regularity and simplicity. In this paper, the design of a 16-bit comparator is proposed. Magnitude comparison is one of the basic functions used for sorting in microprocessor and digital signal processing, so a high performance effective magnitude comparator is required.
