: There is a need for high speed Analog to digital Converters, ultra low power and area efficient circuits. Hence designing high speed comparators is more challenging, when supply is smaller i.e. in a given technology to achieve high speed larger transistors are required to compensate the reduction of supply voltage, which also mean that more due area and power is required. To improve the speed and delay the Dynamic regenerative comparators is used. In this paper, a double tail comparator is proposed and executed in tanner tool version 13.0 using S-EDIT. Its schematic and waveform is analyzed and after analysis it is observed that from single tail to double tail comparator delay has been reduced by 26 ns i.e. 5 times although its power is increased to two fold. By changing the aspect ratio of transistors we can achieve less delay. Based on requirement one can opt for either high speed or low voltage circuits
