TWO STAGE ANALOG-TO-DIGITAL CONVERTER FOR HIGH-SPEED IMAGE SENSOR |
摘要 |
The present invention relates to a two- or multiple-stage analog to digital converter. The converter preferably includes an incremental ADC in the first stage. The incremental ADC comprises an integrator and a comparator. After the predefined number of comparisons performed by the comparator, the output of the integrator appropriately scaled is provided to the second stage where it is further sampled. In particular, the scaling gain is inversely proportional to the integrator gain. The second ADC performs the conversion of the remaining least significant bits and then the output of both stages is combined. Moreover, a calibration and correction approaches are provided for the multi-stage ADC. |
