Comparators are most commonly use and basic blocks of analog-to-digital converters. For the purpose of increasing speed and also for lesser power and delay circuits needed high-speed comparators. It is very difficult and challenging to design high-speed comparators when the smaller of supply voltages. In this paper, a new double-tail comparator i.e inverter based double-tail comparator is implemented with lesser power, high speed and low-voltages based on the results of conventional double-tail and proposed double-tail comparators. When compared to the results of conventional and proposed double-tail comparators, a new inverter based double-tail comparator gives better performance in terms of delay and power. this project is done with tanner tools in 180nm technology. output waveforms will be shown in w-edit.
