4-Bit Magnitude Comparator Design Using Different Logic Style

Abstract

 ABSTRACT: 4-bit magnitude comparator using various logic styles is explained in this. Comparison is one of the common arithmetic operation that is used to determine which number is  greater, equal to, or less. Every device from op-amp to Alu needs  to performs comparison operation. At designing level , comparator can be designed using different  logic styles . Here comparison is done for simple 4-Bit combinational comparator and cascaded comparator. Results for  different designs is presented in form of  simulations that is performed on Cadence virtuoso at 180nm technology .

 Keywords –– comparator, arithmetic, virtuoso , cascaded
