Complies with the regulations of the University and meets the accepted standards with respect to originality and quality. Batteries, ultra capacitors (UCs), and fuel cells (FCs) are widely being proposed for electric and plug-in hybrid electric vehicles (EVs/PHEVs) as energy sources. The increasing popularity of EVs and PHEVs can be attributed to the savings in fuel costs, compared to conventio...

This paper reports how VLSI cost metrics (area, delay, power) of residue reverse converters scale with the cardinality and dynamic range of moduli sets. The study uses CMAC reverse converters, reported previously by the authors to be the most efficient known to date in terms of area and delay. In all, 134 reverse converters with dynamic ranges from 32 to 120 bits and set cardinalities ranging f...
