Abstract

We present the experimental results obtained with TOFPET2, a readout and digitization ASIC for radiation detectors using Silicon Photomultipliers. The circuit is designed in CMOS 110 nm technology, has 64 independent channels and is optimized for time-of-flight measurement in PET or other applications. The chip has quad-buffered TDCs and charge integration ADCs in each channel. The chip tape-out was done in September 2016 and first tests started in beginning March 2017. Coincidence Time Resolution (CTR) of 164ps FWHM has been measured with ²²Na point source. The energy resolution achieved for the 511keV peak is 10.5% FWHM.
