Recent developments in fast timing ASICs for particle physics and medical imaging

This paper will cover recent developments and trends in ASICs designed by Weeroc and its affiliated laboratory, OMEGA (IN2P3/CNRS/Ecole Polytechnique), for medical imaging and particle physics applications. Two categories of ASIC will be reviewed: ASICs for medical imaging (e.g., TOF-PET) which have been designed for obtaining the lowest CTR (sub 100 ps RMS) and ASICs in particles physics which are driven by readout of fast silicon sensors in the HL-LHC upgrade program.
