A High Dynamic Range ASIC for Time of Flight PET with monolithic crystals
Proceedings of Topical Workshop on Electronics for Particle Physics — PoS(TWEPP2018)
The HRFlexToT is a 16-channel ASIC for SiPM anode readout designed for Positron Emission Tomography (PET) applications that features high dynamic range (>8 bits), low input impedance, common cathode connection, high speed and low power (≈3.5 mW/ch). The ASIC has been manufactured using XFAB 0.18 µm CMOS technology. The main characteristics of the HRFlexToT, compared to its predecessor, are a new energy measurement readout providing a linear Time Over Threshold (ToT) with an extended dynamicdoi:10.22323/1.343.0085 fatcat:rvj6esdxqjg5ric4acnftph3xm
