An A/D converter calibration apparatus of the "skip-and-fill" type includes a set of operating condition parameter sensors (100) for detecting the current operating conditions, which are represented by parameters x1,..., xN. The measured parameter are forwarded to an operating conditions change detector (102), which calculates a change measure and determines whether this measure exceeds or falls below a predetermined change threshold. A calibration control signal CTRL_SKP_RT is passed to a calibration control unit (104), which sets the background calibration skip rate to a high value if the measure exceeds the threshold an to a low value if it does not exceed the threshold. |
