Patent 7115963 was granted and assigned to Quantum Semiconductor LLC on October, 2006 by the United States Patent and Trademark Office.
In-pixel circuit architectures for CMOS image sensors are disclosed, which are suitable for avalanche photo-diodes operating either in linear or in non-linear mode. These architectures apply in particular to photo-diodes and image sensors in which CMOS devices are fabricated on thin-film silicon-on-insulator substrates.
