Abstract

This paper presents a 92k SPAD, 16×8 pixel sensor for PET imaging, implemented in 0.13μm low voltage CIS technology. Within each pixel, 720 SPADs are organized into high fill factor mini-SiPMs placed around a central logic block. The sensor demonstrates a new architecture for this application, providing a 100Msamples/s real time energy histogramming capability, as well as an on-chip discriminator for the recognition of gamma events and integration control for the automatic acquisition of event data. Preliminary gamma measurements demonstrate an energy resolution of 13.1% at 20ºC, improving to 11.3% at -20ºC.
