Abstract:
An error compensation correction device for a pipeline analog-to-digital converter includes a correction pipeline stage and a conventional pipeline stage. For each correction pipeline stage, a corresponding error estimation circuit, a level edge detection circuit, a random level generation circuit, and MUX circuit being provided. The present disclosure can track and correct non-ideal properties and mismatching errors in real time over time along with the change of the surroundings without interrupting the ADC normal work of the pipeline. Thus the correction value is closer to the real situation.
