Fig. 1From: Evaluation of the PETsys TOFPET2 ASIC in multi-channel coincidence experimentsSchematic drawing of the TOFPET2 channel trigger circuit. In the timing branch of the trigger circuit, the output of the first discriminator D_T1 is delay by a configurable delay element with respect to the output of the second discriminator D_T2. The design allows the rejection of small noise pulsesBack to article page
