A HIGH-SPEED TREE-BASED 64-BIT CMOS BINARY COMPARATOR

Anjuli, Satyajit Anand

Abstract: A high-speed tree-based 64-bit CMOS binary comparator is proposed in this brief. Comparison is most basic arithmetic operation that determines if one number is greater than, equal to, or less than the other number. Comparator is most fundamental component that performs comparison operation. This brief presents comparison of modified and existing 64-bit binary comparator designs concentrating on delay. Means some modifications are done in existing 64-bit binary comparator design to improve the speed of the circuit. Comparison between modified and existing 64-bit binary comparator designs is calculated by simulation that is performed at 90nm technology in Tanner EDA Tool

Keywords: Binary comparator, digital arithmetic, high-speed
