Abstract
The framework of the readout electronics system for the CEPC reference detector has been designed based on background simulations and the baseline design of sub-detectors. To maximize the possibility of new physics exploration, an architecture of front-end triggerless readout with a full back-end trigger has been chosen as the baseline. The detector front-end electronics will be mostly implemented with ASICs to the radiation tolerance requirements. Inspired from CERN common projects such as lpGBT, Versatile Link and bPol, a common data interface, realized by a chip-set FEDI (Front-End Data Interface ASIC), and a common power module PAL (Power At Load), will be used for all the sub-detector electronics. The back-end electronics can thus also benefit from this architecture, which features a unique interface protocol, and can be commonly designed for all sub-detectors. In this talk, we will introduce the overall design of CEPC sub-detectors electronics with their general requirements, the latest R&Ds, especially the ASICs and the common interface system. In the end, our research team will be introduced and the effort related to the DRD7 will be discussed.
