2 Achieving Accuracy Through Calibration

Several factors can contribute to the degradation or loss of calibration in a high-speed ADC. These factors can affect the accuracy and performance target of the ADC, leading to a point where re-calibration is necessary. The following section discuss some common factors that can cause a high-speed ADC to become uncalibrated.
