Abstract

present an integrated analog front-end for the readout of a non-linear DEPFET Sensor with Signal Compression (DSSC). The DSSC system, currently under development, is a 1-Mega pixel detector system for the European X-ray Free Electron Laser (XFEL) in Hamburg. It will record Xray images with a maximum frame rate of 4.5MHz and will achieve at the same time a single photon resolution at 1keV and a high dynamic range. Two different readout strategies of the DEPFET pixel, Source Follower (SF) and Drain Readout (DR), have been fabricated in the 1.2V 0.13 mu m IBM CMOS technology. Both solutions share the same analog filter based on a new architecture that implements a trapezoidal shaping function employing only one operational amplifier. In this paper, the architecture of the analog front-end relative to both the readout strategies and of the new designed filter and the performance of the test chips are presented.
