Description
Abstract. In this talk we look at digital SiPMs as an alternative to analog SiPMs, analyzing pros and cons of the two architectures, systematically from a theoretical and a practical perspective. The key advantage of digital SiPMs is not higher timing accuracy or better noise but rather higher tolerance to environmental variations and higher long-term robustness. Moreover, thanks to the capability of controlling each SPAD cell individually, trade-offs between dark count rate and photon detection efficiency can be fine tuned depending on the application. For these reasons, digital SiPMs are particularly indicated for Brain PET scanners, where flexibility, reliability, and portability are key.
