A system for digitizing the magnitude of a first parameter, which can be inferred by applying to a second parameter and digitizing the magnitude of a resulting third parameter. The circuit which applies the second parameter has an associated bias point with which the magnitude of the second parameter varies. The value of the first parameter can result in an error in the value of the second parameter which results in an error being incurred when the digitized value of the third magnitude is used to infer a digitized value of the magnitude of the first parameter. This is avoided by adjusting the bias point with each successive trial and employing a sequential-trial ADC which performs sequential comparisons between the third magnitude and respective decision thresholds, such that there is no error in the magnitude of the second parameter when the third magnitude is equal to the decision threshold for a particular trial. |
