Abstract
We present a 25.2-Mpixel, 120-frames /s full-frame global shutter CMOS image sensor (CIS) featuring pixel-parallel analog-to-digital converters (ADCs). The sensor addresses the limitations of conventional rolling shutters (RSs)—including motion distortion, flicker artifacts, and flash banding—while maintaining image quality suitable for professional and advanced amateur photography. A stacked architecture with 3- µm-pitch Cu–Cu hybrid bonding enables more than 50 million direct connections between
