Abstract :
A unified description of the correlation-based techniques for background calibration of pipeline ADCs using additive modulation at the MDAC output is presented in this paper. Two different algorithms for full calibration of this kind of converter which at least a factor 2 improvement in convergence speed, memory resources and stage output swing requirements over previous MDAC modulation approaches are also proposed.
