Abstract

Spectroscopy is a key scientific technique to study the interaction of matter and electromagnetic radiation namely light. To make it possible, joint efforts are required where the integrated-circuit (IC) plays a major role. With today’s advances in CMOS technologies, increasing high-sensitivity and high-dynamic range becomes essential to cope with increasing demands of today’s applications. This paper proposes an InGaAs back-illuminated line-scan array of pixels adapted for new generations of spectroscopy imagers. It allows an effective 40-kHz frame-rate and 84dB dynamic range measured at low-gain for one frame and consumes only 16mA making it highly compatible with portable applications. The sensor proved a wide spectral range (0.9um to 2.1um) hence enabling application in the near infrared and short-wave domains.

Dr. Sassi BEN AZIZA received the PhD degree in nano-electronics and nano-technologies from the university of Grenoble-Alpes, France in 2018. His doctoral research was directed towards analog-to-digital conversion for CMOS image sensors in the visible. After his post-doc, he followed-up with read-out design for Infrared image sensors where he is currently senior analog-and-mixed signal IC designer at Xenics Infrared Solutions (part of Exosens group).
