Abstract

This paper explores the implementation of global shutter functionality in a 4T pixel for CMOS sensors, addressing the shortcomings of conventional 4T pixels through the introduction of a horizontal anti-blooming (AB) channel. By analyzing preliminary results from a 16Mpix sensor developed for motion analysis applications, the study demonstrates improved global shutter performance and discusses the effects of different dosages in the AB channel on pixel operation.
