Samsung developed two types of new sensor. This are small sensors only and they will not find his use in next Samsung DSLR’s. But both new sensors do have really advanced tecnology! Sensor “1″ reords video in 120frame/s ! Sensor “2″ has a new low-noise tecnology.

1)  2.1Mpixel 120frame/s CMOS Image Sensor with Column-Parallel ΔΣ ADC Architecture

A 2.1Mpixel 120frame/s CMOS image sensor with column-parallel ΔΣ ADCs is realized in a 0.13μm CMOS process. Column-parallel ΔΣ ADC architectures improve the conversion speed while reducing the random noise level as well. Inverter-based SC circuits maximize the power efficiency. This sensor achieves a measured noise floor of 1.9e-, while dissipating 180mW.

2)  1.1e- Temporal Noise 1/3.2-inch 8Mpixel CMOS Image Sensor using Pseudo-Multiple Sampling

A pseudo-multiple sampling technique for a low-noise CIS is implemented using a conventional column-parallel single-slope ADC structure with no additional circuitry. It is applied to a 1/3.2-inch 8Mpixel CIS. Measurement results show the technique effectively reduces dark temporal noise from 1.6e- to 1.2e- in 10b ADC mode, and from 1.8e- to 1.1e- in 12b ADC mode.
