Due to non-ideal effects like a mismatch between internal components, the actual transfer function of an ADC deviates from the ideal staircase response. The offset error shifts the transfer function along the horizontal axis and hence causes a shift in the code transition points. The purple curve in Figure 2 shows … See more The ideal transfer function for a 3-bit unipolar ADC is shown in Figure 1. Ideally, the ADC exhibits a uniform staircase input-output characteristic. … See more With the offset error eliminated, the first transition of the actual response coincides with that of the ideal characteristic. However, this doesn’t guarantee that the other transitions for the two characteristic curves will also occur … See more It is worth mentioning that some ADC specifications are not consistently defined in technical literature. One confusing inconsistency is the sign of the offset and gain error.
