Abstract :
In this work, a bionic sensory chip based on the CNN model derived from the mammalian retina is proposed. A CMOS compatible sensory chip is designed based on the CNN model to mimic functions of photoreceptor and horizontal cell of the mammalian retina. The sensory chip contains a focal plane array of 32×32 similar pixels that perform functions of photoreceptor and horizontal cell. Spatial and temporal characteristics of a one-dimensional array are verified via HSPICE simulations in this paper, while a two-dimensional array of 32×32 cells is to be fabricated to investigate real-time images obtained by this bionic sensory chip.
