This paper presents the design and characteristics of a front-end readout application-specific integrated circuit (ASIC) dedicated to a multichannel-plate photodetector coupled to LYSO scintillating crystals. In our configuration, the crystals are oriented in the axial direction readout on both sides by individual photodetector channels allowing the spatial(More)
This paper presents the design of a high accuracy multichannel peak detect and hold (PDH) circuit. This PDH measures the energy of an event and is one part of a readout chain for avalanche photo diodes (APD)-based positron emission tomography (PET) imaging. The circuit is designed in a 0.35μm CMOS process. The proposed PDH is dedicated to ultra low(More)
