Time of flight (TOF) measurements in positron emission tomography (PET) are very challenging in terms of timing performance, and should ideally achieve less than 100 ps FWHM precision. We present a time-based differential technique to read out silicon photomultipliers (SiPMs) which has less than 20 ps FWHM electronic jitter. The novel readout is a fast front end circuit (NINO) based on a first stage...
STiC-Silicon Photomultipler (SiPM) Timing Chip, is a prtotype ASIC with 4 channels dedicated to fast timing discrimination in Positron Emmission Tomography using SiPM. It is designed in AMS 0.35μm CMOS technology. Each single channel of the chip can be operated either in constant fraction (CF) or leading edge (LE) triggering mode. The basic principle of the SiPM readout is to sink the current signal...
Silicon photomultipliers (SiPMs) are a novel type of solid state photon detectors with similar internal gain factors as Photomultiplier Tubes (PMTs). Due to their low operation bias voltage, magnetic field immunity and small size, these new silicon photon detectors can be used for a wide range of applications, in particular Positron Emission Tomography (PET). Using combined crystal/SiPM systems for...
