Abstract :
In this paper, novel compact counter/memory circuits are proposed for spiking pixels. The proposed in-pixel circuits combine digitizing and memory functions, and use Gray code to limit switching activity and read-out error. Three possible implementations are proposed to meet the requirements of speed, pixel fill-factor and dynamic range.
