TL;DR: SymPET is a high-resolution TOF PET readout microchip with low power consumption and high channel density. It includes features such as fully random accessible analog storage, input triggering, and on-chip biasing, control and waveform feature extraction capabilities. Preliminary results show that SymPET can provide less than 10 ps timing jitter at a reasonable power budget.
