Abstract

recently proposed XOR-based Digital Silicon
Photomultiplier is compared against the OR-based counterpart.
We show experimental data from a set of SPAD pixel
arrays in 130nm CMOS process with selectable OR tree and
XOR tree for direct comparison. We demonstrate how XOR based
dSiPMs solve the limitation caused by monostable
circuits and reach higher maximum count rates compared
to optimised OR-based dSiPMs. The increased throughput
of the SPAD array allows higher sampling rates for the
digitisation of the light signal enhancing dynamic range and
linearity.
