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 … Visa mer 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. Note that an output code doesn’t correspond to a single analog input value. … Visa mer 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 … Visa mer 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. For … Visa mer Building on the concepts discussed above, we can define the gain error in terms of the full-scale error.
