In this paper a new method of linearized settling error calibration for a pipeline A/D converter is proposed. The pipeline A/D converter employs non-slewing amplifiers for linearizing the settling error. A prototype 15b pipeline A/D converter was fabricated in 0.25 µm process. The calibration is carried out by adjusting gradients and offsets of the linearized settling error. The calibration of the settling error improves the SNDR and SFDR from 68 dB and 74 dB to 72 dB and 88 dB, respectively, at 35MS/s.
