BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@booklet{EasyChair:2257,
author = {Jehad Ahmad Ghanim and Ali Shatanawi},
title = {Determine the Interconnection of a Hardware Implementation for DSP Applications},
howpublished = {EasyChair Preprint 2257},
year = {EasyChair, 2020}}
