Publication number: 20240089639Abstract: A global shutter image sensor with improved pixel failure coverage detects failures caused by the pixel chip of the image sensor. The global shutter image sensor includes a pixel chip including an array of photodiodes and associated logic, and a logic chip, bonded to the pixel chip, including an array of logic blocks for processing the images detected by the photodiodes. A failure detection circuit coupled to a reference voltage node of the image sensor detects a failure in the pixel chip by capturing a first level of pixel bias current and a second level of pixel bias current wherein a difference between the first level and the second level drives an output of the failure detection circuit either as logic high or as logic low.Type: ApplicationFiled: September 8, 2022Publication date: March 14, 2024Inventors: Liang ZUO, Zhenfu TIAN, Jiayu GUO, Dennis LEE, Zhiqiang SONG
