Design of Self-Calibration Comparator for 12-Bit SAR ADCs

Round 1

Reviewer 1 Report

In this work, the authors designed a self-calibration comparator for 12-bit SAR ADCs. The research appears to be efficiently done and appropriately reported, however, the standard of English is acceptable and only needs a few corrections. Nevertheless, there are some questions and corrections that must be answered to improve and complete the document.

 

Abstract section: The abstract is a little bit confusing and misses some information like more results and conclusions, I suggest to authors follow these rules:

A. One or two sentences on BACKGROUND

B. Two or three sentences on METHODS

C. Less than two sentences on RESULTS

D. One sentence on CONCLUSIONS

Introduction section: In this section, the authors don’t indicate the novelty of their work. what is the innovation of your work when compared with the other researchers? The "Knowledge gap to be filled"? In this introduction, the authors must describe or indicate the work that will be done to test their "hypothesis".

In the final table and in the abstract, it is necessary to give an estimate of the ENOB (EFFECTIVE NUMBER OF BITS) and the the figure of merit (FOM) and an explanation of the quality of this figure of merit, that is, this quantity.

I suggest you include references about dynamic comparators and discuss them in the introduction section. For example, references with DOI: 10.1145/3338852.3339857 and DOI: 10.1109/JSEN.2019.2891307

In lines 171, 254, 299. Please change the word “Formula” to “Equation”.

Reviewer 2 Report

Successive approximation register analog to digital converters (SAR ADCs) is widely used in sensing detection, industrial control and other fields because of its simple structure and low power consumption. The main element of the SAR ADC is the comparator. Its characteristics have an important influence on the functioning of the SAR ADC. Therefore, the topic of the reviewed manuscript is relevant.

The authors made a detailed analysis of the sources of information and proposed a new circuit SAR ADC. This new circuit has certain advantages over known devices. 

The manuscript is explained with detailed mathematical calculations and research results. The illustrations are done on a good level.

One small remark. In Table 2 (line 460) the meaning of number 5 is not clear.

Therefore, I think it is appropriate to accept the article after minor revision.

Round 2

Reviewer 1 Report

The second version of the manuscript improved significantly when compared with the first version. So, in my opinion, the manuscript can be accepted for publication.

The standard of English is acceptable only needs a few corrections.
