Low Noise Global Shutter Image Sensor Working in the Charge Domain
Abstract
In this letter, we present global shutter (GS) pixel using active deep trench isolation gate to transfer and store photodiode charge signal into a fully depleted pinned MOS capacitance. This architecture is compatible with conventional correlated double sampling. GS readout noise lower than 2e- is demonstrated. The fully depleted pinned capacitance is able to store 12ke- with dark current lower than 25e-/s at 60 °C. The GS efficiency, better than 99.96% at 550nm, is reported.
