This paper presents a new quenching circuit (QC) and single photon avalanche diode (SPAD) implemented in TSMC CMOS 65 nm technology. The QC was optimized for timing resolution (SPTR) with view to an implementation 3D digital SiPM. presented has jitter of 4 ps full width at half maximum (FWHM) the SPAD 7.8 FWHM SPTR. adjustable threshold allows optimization as well excess voltage rise time characterization. threshold, hold-off recharge are essential optimize performances each SPAD. also...
Time-of-flight measurements are becoming essential to the advancement of several fields, such as preclinical positron emission tomography and high energy physics. Recent developments in single photon avalanche diode (SPAD)-based detectors have spawned a great interest digital silicon photomultipliers (dSiPMs). To overcome tradeoff between photosensitive area processing capabilities current 2-D dSiPM, we propose novel 3-D SiPM, where SPAD, designed for maximal area, will be stacked over...

For decades, fast neutron radiography performed using pulse-counting detectors employed PMTs coupled to plastic scintillator pixel arrays. SiPM-based systems are now sought replace fragile PMTs, but conventional, "analog" SiPMs suffer from intrinsic limitations which limit their achievable performance. Among these limitations, a complete analog readout and digitizer chain is required, counterintuitive approach when considering that the single-photon avalanche diode (SPAD), basic unit cell of...
