Latest Patents

Nagaraja Satyadev holds a patent for a "High dynamic range sensor with blooming drain." This invention features an image sensor that incorporates at least two photodiodes in each unit pixel. The design achieves a high dynamic range by selecting different exposure times for the photodiodes. Additionally, it effectively reduces blooming. The readout timing cycle is strategically chosen so that the short exposure time photodiodes function as drains for excess charge that overflows from the long exposure time photodiodes. To further enhance the draining of excess charge, the arrangement of photodiodes is optimized, ensuring that long exposure time photodiodes are surrounded by short exposure time photodiodes in both vertical and horizontal directions. Furthermore, a micro-lens array may be included to preferentially couple light to the long exposure time photodiodes, thereby improving sensitivity.
