Hi,I wonder how these in-pixel analog memories are implemented so its content is not degraded by light induced current leakage. Regards
The well structure (p-well on n-sub) helps reduce electrical crosstalk, and hence, parasitic light sensitivity (PLS). Pixels built on p-epi/p+sub suffer more from this issue.
