DESIGN OF LOW POWER AND HIGH SPEED DOUBLE TAIL COMPARATOR USING CLOCK GATING METHOD

Comparators are the basic elements for designing the modern analog and mixed signal systems. The speed and area is main factors for high speed applications. Various types of dynamic double tail comparators are compared in terms of Delay, Area, Power, Glitches, Speed and average time. The accuracy of comparators it mainly defined by its power consumption and speed. The comparators are mainly achieving the overall higher performance of ADC. The high speed comparators suffer from low voltage supply. Threshold voltage of the device is not scaled at the same time, as the supply voltage of the device. In modern CMOS technology the double tail comparator is designed by a using the dynamic method, it mainly reduces the power and voltage. The analytical expression method it can obtain an intuition about the contributors, comparator delay and explore the trade-off dynamic comparator design
