Two-Dimensional Integrated Circuits for Hybrid Solid-State Pixel Detectors

We have developed custom two-dimensional (2-D) mixed signal readout integrated circuits (ICs) for advanced position sensitive hybrid solid-state radiation detectors. The 2-D readout ICs are an integral part of hybrid semiconductor pixel detectors developed for X-ray, gamma-ray and charged particle imaging. Different detector applications require custom IC, which is typically designed for a specific 2-D detector array. Therefore, it is challenging to develop generic ICs to meet a range of applications in different complementing fields. To approach this aim NOVA has put significant effort on developing its ICs as flexible as possible to address differences in the fields of application. Therefore, these ICs embody versatile and adaptable functions as well as selectable features. An overview of 2-D ICs recently developed at NOVA and their functionality and features will be presented. Preliminary test results will be discussed. These ICs can be used for applications ranging from X-ray astronomy and medical imaging to munitions, security and industrial inspection. Some potential applications are: gamma camera; SPECT; PET; CT; digital mammography & radiography; baggage scanner; NDI and NDE.
