Abstract: In conventional double tail comparators, Kick-back noise is produced and the circuit requires high input impedance. Due to aggressive scaling of MOS, short channel effects occur and there is a need of substitutes like FinFETS. In this paper, we have designed double tail comparator by using FinFET technology in shorted gate mode. It is seen from results that the power and delay are reduced in a large quantity maintaining the output waveforms to the previous one. This improves efficiency of the system and noise tolerance and leakage current are also reduced. This can be beneficial for the Analog to Digital Converters, reference voltage comparison.
