Omnivision Proposes DTI with Charge Transfer Assist

Omnivision patent application US20150048427 "Image sensor pixel cell with switched deep trench isolation structure" by Sing-chung Hu, Rongsheng Yang, Gang Chen, Howard E. Rhodes, Sohei Manabe, and Hsin-chih Tai proposes a BSI pixel with DTI, filled by a lightly doped poly. A negative pulse applied to the DTI poly allows increasing PD doping and full well while maintaining a low image lag:

ISSCC 2015 Report: Shizuoka University Compressive Imager

Albert Theuwissen continues to post his reports from ISSCC. Shizuoka University presents a 200 million fps compressive imager. The imager consists of 15 pixel sub-arrays, each of them exposed at the differing times. In the end, a 200Mfps image sequence is recovered.
