چکیده
Abstract — A new dynamic comparator is proposed and it is compared with two existing comparators in terms of voltage, delay and frequency. CMOS dynamic comparator which has dual input, dual output inverter stage suitable for high speed ADCs with low voltage and low power dissipation. A conventional comparator is replaced with dynamic comparator which reduces the delay and voltage which increases the speed. The technology scaling of MOS transistors enables low voltage and low delay which decreases the offset voltage of the comparator. The proposed system has less number of voltage and delay when compared to other comparators. The need for ultra low-power, area efficient, and high speed analog-to-digital converters is pushing toward the use of dynamic regenerative comparators to maximize speed and power efficiency.

In traditional comparators especially for ADCs, one serious problem is the kick back noise, which disturbs the input signal voltages and consequently might cause errors at the outputs of the ADCs. In this paper, we will work on a novel ultra low-power rail-to-rail CMOS latched comparator with very low kickback noise for low to medium speed ADCs. This comparator adopts a preamplifier followed by...

The analog-to-digital converter (ADC) is an essential part of system-on-chip (SoC) products because it bridges the gap between the analog physical world and the digital logical world. In the digital domain, low power and low voltage requirements are becoming more important issues as the channel length of MOSFET shrinks below 0.25 sub-micron values. Moreover, SoC trends force ADCs to be integrat...
