Abstract:

The general requirements and development trends of CMOS image sensors for consumer electronics and machine vision are high resolution, high sensitivity, and wide spectral dynamic fast response. Over the past 30 years, academia and industry have put significant efforts and attempts on researching and designing advanced photodetectors, pixel circuits, and fabrication processes, including the adoption of new materials and processes, as well as the proposal and evolution of various active pixel sensor circuits. These technologies have made CMOS image sensors a great success and led to a multi-billion dollar business that continues to grow particularly with the emergence of applications in AR/VRs, artificial intelligence, and autonomous driving, however, how to simultaneously achieve high resolution, high sensitivity, and wide dynamic range at low power consumption and computation cost, still remains as a great challenge. 

Inspired by the working principles of human retina and neuromorphic computing, this talk will address the retinomorphic design and architecture, and discusses latest research and development on pixel and neuromorphic circuits for enabling retinomorphic spike vision sensors.
