Reversible logic has attracted substantial interest due to its low power consumption which is the main concern of low power VLSI systems.In this paper, a novel 4x4 reversible gate called inventive gate has been introduced and using this gate 1-bit, 2-bit, 8-bit, 32-bit and n-bit group-based reversible comparator have been constructed with low value of reversible parameters.The MOS transistor realizations of 1-bit, 2bit, and 8-bit of reversible comparator are also presented and finding power, delay and power delay product (PDP) with appropriate aspect ratio W/L.Novel inventive gate has the ability to use as an n-to-2n decoder.Different novel reversible circuit design style is compared with the existing ones.The relative results shows that the novel reversible gate wide utility, group-based reversible comparator outperforms the present style in terms of number of gates, garbage outputs and constant input.
