Abstract

A pixel arrangement comprises a photodiode, a circuit node, a transfer transistor coupled to the photodiode and to the circuit node, an amplifier with an input coupled to the circuit node, a first and a second capacitor, a first transistor coupled to an output of the amplifier and to the first capacitor, a second transistor coupled to the first transistor and to the second capacitor, and a coupling transistor coupled to the circuit node and to the second capacitor.
