A SiPM-Readout ASIC for SPECT Applications

In this paper, we present ANGUS, an application specific integrated circuit (ASIC) for silicon photomultiplier (SiPM) readout designed for low-energy gamma imaging (140 keV), specifically targeting clinical single photon emission computed tomography (SPECT) applications based on Angertype detectors. The chip is composed of 36 channels, each featuring a current conveyor input followed by an RC filt...
