VLSI Implementation of a Neuromorphic Spiking Pixel and Investigation of Various Focal-Plane Excitation Schemes

Abstract

In this paper we describe a Neuromorphic spiking pixel architecture allowing the conversion of the light intensity into a pulse train signal. We first describe the spiking pixel architecture and its inherent advantages such as light adaptation mechanism and linear response characteristics. Inspired from biological visual systems and the integrate and fire oscillator, different inter-pixels interaction schemes are studied and their synchronization ability are compared. The spiking pixel architecture was implemented and the functionality of the spiking pixel imager is demonstrated through experimental results.
