This paper presents a low power comparator used in designing of Successive Approximation Register (SAR) ADC. A simple topology of SAR ADC design consideration A typical SAR ADC consists of three components: DAC, comparator, and SAR logic. It has become a superior ADC topology with a good tradeoff between power consumption, speed, and resolution. As shown in the above algorithm, a SAR ADC requires: An input voltage source V in.

This paper presents a low power comparator used in designing of Successive Approximation Register (SAR) ADC. A simple topology of Together with the increasingly demanding DAC, the design of the comparator introduces a big challenge for the implementation of high resolution SAR ADCs. Therefore, several state of the art works investigated improved comparator architectures aiming for higher resolution. However, those architectures in most cases resulted either in excessive power consumption or compromised conversion speed beginning from a single SAR ADC and moving to various hybrid architectures. At the end of this overview, a recently reported compact and high-speed SAR-Flash ADC is introduced as one design example of SAR-based hybrid ADC architecture.

Design and Simulation of Comparator Architectures for Various ADC. Applications the DAC of a Non-binary Redundant SAR ADCs," 2018 31st. International 

Since you are looking at using the SAR for calibration, you are not really aiming at speed and I guess you can afford to add autozeroing to your clocked comparator. reason, the group decided to use the SAR architecture for its 65nm ADC. This thesis describes the design port of a comparator for a SAR ADC in digital still camera and camcorder applications, from the 65nm to 0.11pm process node. The two processes have similar characteristics and both operate off a 1.2V supply.
