description: The aim of this thesis was to verify the feasibility of a readout ASIC which fulfills the challenging requirements of the X-ray Integrating Detector (XIDer) project. XIDer is committed to the design of a 2D hybrid pixelated detector for X-ray diffraction experiments at accelerator-based fourth-generation X-ray sources like the European Synchrotron Radiation Facility (ESRF). The requirements include a wide dynamic photon counting range up to 1 × 10^11 ph s^(−1) mm^(−2) with single photon sensitivity and a high versatility for many different measurement conditions. In addition, the energy range of 30 keV to 100keV demands for the use of high-Z compound semiconductor sensor materials like cadmium telluride and cadmium zinc telluride. The proposed and implemented readout ASIC design follows a modularized approach to read out large sensor pixel matrices in parallel performing on-chip analog-to-digital conversion, data pre-processing and storage. It explores novel concepts like a pipelined continuous conversion front-end, the digital integration scheme and the telegram protocol.  This thesis presents the ASIC’s design process from drafts to actual implementations. Design concepts, simulations and characterisation measurements of ASIC and ASIC-sensor assembly prototypes are explained, analyzed and discussed with an emphasis on the performance of the analog front-end.
