Shizuoka University, Japan, publishes PhD Thesis "A Study on High-Speed Low-Noise Readout Architectures and Column A/D Converters for CMOS Image Sensors" by Tongxi Wang. The thesis starts with a nice overview of the readout and column-parallel ADC concepts:
A Hybrid Tri-Stage-Pipeline Column ADC (TSP) architecture is proposed to achieve the better trade-offs (implemented in 65nm process):
Another proposal is Folding-Integration/Cyclic Cascaded ADC (FICC) (implemented in 110nm process):
