Hybrid pixel radiation detectors with a direct photon-to-charge conversion working in a single photon counting mode have gained increasing attention due to their high dynamic range and noiseless imaging. Since sensors of different materials can be attached to readout electronics, they enable work with a wide range of photon energies. The charge-sharing effect observed in segmented devices, such as...
This paper presents an analyze of various hit allocation algorithms for pixel readout circuits, which aim to compensate the charge sharing effect. A comprehensive pixel readout circuit model, which allows to measure the missed/false hit probability and hit allocation accuracy is described in detail. The presented simulation results compare the performance of existing algorithms in comparison with...
The paper presents a highly efficient system for automated wafer testing implemented on a single software platform. Building fully functional device requires often expensive and time consuming, manufacturing steps. Thus, the ASICs on the wafer ought to be tested in advance to ensure that only the chips with no manufacturing defects will be used in the further process. The presented testing system...
