Design of 8-Bit Comparator Using 45nm CMOS Technology
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 6
Abstract
In this paper design of 8- bit binary comparator using 45nm CMOS technology is discussed. This design needs less area and less number of transistors, also discussed about power and execution time. The circuit has three output X, Y and Z. X is active high, when A>B, Y is active high when A=B and Z is active high when both X and Y are active low. Design 1- bit comparator with the help of precharge gate.The design of 1-bit comparator has been extended to implement an 8-bit comparator by connecting in series with pass transistor between them. The design has been implemented in Microwind3.1, is tested successfully and has been validated using Pspice for different measurable parameter.
