Albert Theuwissen starts publishing his overview of ISSCC 2015 imaging session. The first part talks about the new Sony 20MP/1.43um stacked sensor with two ADCs per column. The dual ADC can be used:
- for increased readout speed (120fps in 16MP/10b mode)
- for 3db noise improvement
- to achieve 1.3e- noise level by multiple reads
- simultaneous stills and video capture
