VLSI IMPLEMENTATION OF A NEUROMORPHIC SPIKING PIXEL AND INVESTIGATION OF VARIOUS FOCAL-PLANE EXCITATION SCHEMES

摘要

The author describes a neuromorphic spiking pixel architecture allowing conversion of light intensity into a pulse train signal. The article first describes the spiking pixel architecture and its inherent advantages, such as light adaptation mechanism and linear response characteristics, Inspired by biological visual systems and the integrate and fire oscillator, different interpixels interaction schemes are studied and their synchronization abilities are compared. The spiking pixel architecture is implemented and the functionality of the spiking pixel imager is demonstrated through experimental results
