A continuously calibrated 12-b, 10-MS/s, 3.3-V A/D converter

The continuous calibration of high-linearity, highspeed analog/digital converters (ADCs) can minimize system complexity by allowing a single converter to maintain its accuracy over time. This paper introduces a continuous calibration technique for pipelined and successive approximation ADCs that avoids some of the limitations of earlier designs by performing the calibration in the analog domain. The calibration is made transparent to the overall...
