To describe your comparator in VHDL, use sequential statements in a single process block. Once you have described your circuit in VHDL, you should test your design on the FPGA board. Similar to the ...

A Comparator is a combinational circuit that gives output in terms of A>B, A<B, and A=B. This is entirely expected from the name. A digital comparator’s purpose is to compare numbers and represent ...

This article discusses the implementation of an 8-bit Identity comparator and a 4-bit Magnitude comparator, covering both the concept and the circuit design. We used an Arduino program to execute ...

In this paper, a 4-bit comparator circuit is designed by using Efficient Charge Recovery Logic (ECRL) and Positive Feedback Adiabatic Logic (PFAL). The designed 4-bit comparator circuit is compared ...

The 74HC/HCT85 are 4-bit magnitude comparators which belong to the high-speed Si-gate CMOS devices. ... Circuit simulation made easy. A free online environment where users can create, ... Expandable 4 ...
