AB  - AGIPD is a charge integrating, hybrid pixel readout ASIC, which is under developmentfor the European XFEL. A dynamic gain switching logic at the output of the preamplifier(preamp) is used to provide single photon resolution as well as covering a dynamic range ofat least 1E4 12.4 keV photons. Moreover, at each point of the dynamic range the electronicsnoise should be lower than the Poisson fluctuations, which is especially challenging at the pointsof gain switching.This paper reports on the progress of the chip design on the way to the first full-scale chipAGIPD1.0, focusing on the optimization of the dynamic range and the implementation of protectioncircuits at the preamplifier input to avoid pixel destruction due to high intense spots.
