A 1280×960 Dynamic Vision Sensor with a 4.95-μm Pixel Pitch and Motion Artifact Minimization

This paper reports a 1280×960 DVS. A 4.95-μm pixel pitch is achieved with in-pixel Cu-Cu connection and the newly designed GIDL-suppression scheme. A sequential column selection scheme and a global event-holding function are implemented to minimize motion artifacts. The power consumption per pixel o...

Description
Summary:This paper reports a 1280×960 DVS. A 4.95-μm pixel pitch is achieved with in-pixel Cu-Cu connection and the newly designed GIDL-suppression scheme. A sequential column selection scheme and a global event-holding function are implemented to minimize motion artifacts. The power consumption per pixel of 122 nW is 1.25× smaller and the maximum readout speed of 1.3 Geps is 4.33× faster than the previous state-of-the-art.
