Abstract

The present application relates generally to silicon photomultiplier (SiPM) detector arrays. In one aspect, there is a system including an array of cells each including a single-photon avalanche diode (SPAD) reverse-biased above a breakdown voltage of the SPAD. The system may further include a trigger network configured to generate pulses on a trigger line in response to SPADs of the array undergoing breakdown. The system may still further include a pulse-width filter configured to block pulses on the trigger line whose pulse width is less than a threshold width.
