Abstract

The present description concerns a pixel array comprising one or a plurality of pixels (PIX). Each pixel comprises a first transistor having its control node coupled to a photodiode, a first main conduction node coupled to a first output voltage rail (VS), and a second main conduction node coupled to a second voltage rail (VCS). The array comprises a variable impedance () coupling the first voltage rail (VS) to a first power supply rail (VDD) and a current source () coupling the second voltage rail (VCS) to a second power supply rail (GND), the variable impedance () being controlled based on a voltage on the second voltage rail (VCS). The array comprises a first switch () coupling the second voltage rail (VCS) to a third voltage rail (VINIT).
