This paper reports the design of a 1mW, 10ns-latency mixed signal system in 0.18μm CMOS which enables filtering out uncorrelated background activity in event-based neuromorphic sensors. Background activity (BA) in the output of dynamic vision sensors is caused by thermal noise and junction leakage current acting on switches connected to floating nodes in the pixels. The reported chip generates a pass...
This paper reports the design of a color dynamic and active-pixel vision sensor (C-DAVIS) for robotic vision applications. The C-DAVIS combines monochrome eventgenerating dynamic vision sensor pixels and 5-transistor active pixels sensor (APS) pixels patterned with an RGBW color filter array. The C-DAVIS concurrently outputs rolling or global shutter RGBW coded VGA resolution frames and asynchronous...
