摘要
An analog input voltage is converted to a digital code by, generating a first set of confirmed bits based on a first series of comparisons of an output of a digital-to-analog converter with the analog input voltage and generating a second set of confirmed bits based on a second series of comparisons of the output of the digital-to-analog converter with the analog input voltage. The first set of confirmed bits is independent of the second series of comparisons. The bits of the digital output code corresponding to the analog input voltage are generated based on the first set of confirmed bits, the second set of confirmed bits and a constant value representative of a voltage shift introduced in the digital-to-analog converter between the first series of comparisons and the second series of comparisons.
