The distinctive challenges for design of read-out ASICs for radiation detectors in biomedical applications originate from the need to be interfaced to detectors with high density of pixels and process photons with high rates. Those two dominant factors impose a range of conflicting restrictions and demands on the design of the readout integrated circuits (ROIC). Some of the key challenges are: limited...
Cadmium Zinc Telluride (CZT) and Cadmium Telluride (CdTe) detectors with 200 μm pixellated electrodes were tested with the aim to determine material properties and electrical parameters for hybrid pixel detector (HPD) systems. A 32 channel discrete analogue preamplifier platform was designed and manufactured in which radiation tests were performed on packaged detectors. Although simple in concept,...
The fabricated analog application specific integrated circuit (ASIC) is a front-end circuit for multichannel pixel detector system. The designed ASIC provides signal amplification for a pixelated arrays of 1 mm and 200 ??m pitch pixel detectors made from cadmium telluride (CdTe) and cadmium zinc telluride (CZT) detector. Both the detector and ASIC are combined to target future high intensity research...
