An 8-channel, 46-ps-precision TDC ASIC with improved vernier delay loop for STCF EMC
An 8-channel time-to-digital converter (TDC) with high precision and linearity designed for the electromagneticcalorimeter (EMC) in the Super Tau-charm Facility (STCF) is presented. A 3-level quantization structureis employed in the proposed TDC to achieve high time resolution and wide dynamic range…
