Performance Evaluation of Eight-Channels Picosecond Chip MVT22_8LF

MVT22_8LF is a new multi-voltage threshold (MVT) digitizer implementation. Compared to field-programmable gate array (FPGA) based approaches, application-specific integrated circuit (ASIC) technology can improve integration and resolution capabilities. It can also reduce power consumption. In this work, we comprehensively evaluate the performance of MVT22_8LF, showing a bin size of 19.5 ps, an RMS of 16.2 ps, and inter-channel time evaluation consistency under 1.9 ps. The transition of MVT digitizers from FPGA to ASIC implementation provides a unique opportunity to streamline PET detection systems.
