As promised in comments to the earlier post on sub-electron pixel noise, here is the presentation on the noiseless frame summation in the regular charge-transfer pixel that can allow DR expansion while maintaining the usual 4T pixel noise level:
The above slides complete the description of the noiseless frame summation general idea. There are few practical issues that need to be addressed though:
