A Two-Step Prediction ADC Architecture for Integrated Low Power Image Sensors.

This paper presents a two-step prediction method for the design of low-power column-parallel analog-to-digital converters (ADC) in CMOS image sensors. The proposed prediction method takes advantage of the spatial likelihood of natural scenes, which shows strong correlations between neighboring pixels in the image. Based on this property, the proposed method predicts the MSBs of the selected pixel ...
