Dynamic vision sensor for low power applications

This paper presents the design of a dynamic vision sensor for mobile applications. The sensor features a standby mode with less than 250uW of power dissipation. The sensor changes operation mode between standby and normal operation itself depending on input activity. The power consumption in normal operation mode is typically 500uW and activity dependent. The sensor design is implemented in a 90nm backside illumination process with a pixel-array size of 1.44mm by 1.44mm.
