Abstract
Disclosed is a correcting device of successive approximation analog-to-digital conversion. The correcting device includes a successive approximation register analog-to-digital converter (SAR ADC) and a digital circuit. The SAR ADC is configured to generate a digital output. The digital circuit is configured to determine whether the digital output conforms to a metastable output, and correct the digital output when the digital output conforms to the metastable output. The metastable output is related with a metastable binary comparison-results sequence including successive K comparison results such as 110000 or 001111. The K comparison results include a first comparison result, a second comparison result and successive M comparison results in turn. The first comparison result and the second comparison result are the same; the M comparison results are the same; each of the first comparison result and the second comparison result is different from any of the M comparison results.
