Abstract
An on-chip self testing digital-to-analog converter (DAC) is provided. The functionality of the DAC is measured using a combination of integral non-linearity (INL) and differential non-linearity (DNL). Parts may pass or be rejected based on the testing. When a DAC passes the testing, the process continues to the next DAC or quits if all the DACs have been tested.
