An application specific integrated circuit for multi-anode PMT

The main purpose of this development is to design an “intelligent sensor”, composed of one multi-anode PMT (Hamamatsu H8500), four custom front-end analog chips with embedded analog-to-digital converter and a pre-processing logical unit. The idea of this design is to improve as far as possible the treatment speed of signals of the PMT. This design must be compact to fit the PMT dimensions, in order to combine them together to form an assembly which will be used in medical imaging research, especially for gamma-ray camera at 141 keV (Tc99m) with NaI(Tl) crystal.
