An image-sensing element has an array of photodiodes or other photodetecting elements and performs sigma-delta analog-to-digital conversion on the outputs of the photodetecting elements. The sigma-delta analog-to-digital converters have components divided between pixel-level and row-level structures, with each row-level structure connected to its pixel-level structures to define a multiplexed-input-separated sigma-delta analog-to-digital converter. The converter can include an integrator or can rely on an integration effect of the photodetecting element. The feedback required for sigma-delta analog-to-digital conversion can involve digital-to-analog converters located at each row-level structure or at each pixel-level structure.
