Abstract
A wafer is provided for pre-processing the output currents of detection diodes subjected to thermal radiation, comprising an input stage for integrating the output currents of the diodes and an output stage delivering a signal related the incident radiation by a transfer function. It also comprises transistors for compressing the transfer function, the transistors conducting beyond a shunt threshold current less than a clipping threshold current and having a conduction resistance such as to shunt only a part of the integrated charges.
