The 2023 International Workshop on the High Energy Circular Electron Positron Collider

The development of an energy and time measurement readout ASIC (TEPIX) for gas and large pixel semiconductor detectors is presented. It integrates 128 channel signal processing circuits and is targeting for detectors with pixel size of 0.5 – 2 mm for spectroscopic and imaging applications. Each channel consists of a charge integration front-end, a discriminator, the sample and hold circuits...

As the key component of time measurement electronics, Time-to-Digital Converter (TDC) has become a research hotspot in high energy physics, nuclear medical imaging and radiation detecting. Many TDC topologies have been proposed during the past two decades to realize sub-100 ps time resolution, among which vernier delay loop (VDL) is the most appropriate considering the performance, the design...
