Abstract

See full text

A SAR ADC and an electronic device are disclosed. The SAR ADC includes a read clock generation circuit, configured to connect to a first output terminal and a second output terminal of a dynamic comparator, and generate a read clock signal for reading a first or a second comparison result based on the first and the second comparison result received from the dynamic comparator. The invention reads the comparison result using the read clock signal generated by grabbing the output of the comparator, and can improve the overall analog-to-digital conversion speed of the SAR ADC. Further, the present invention can detect the occurrence of metastable state of the comparator by judging that the output of the comparator has no pulse, and read the comparison result based on the backup clock generated by the operating clock of the comparator.
