论文摘要
在过去几年中,基于定时功能的像素的检测器越来越重要。由于预见的实验条件下的轨道密度较高,因此在山脉界面上进行了近临界的高能物理实验,需要在跟踪中使用时间信息。固态传感器上正在进行各种不同的发展,以在传感器级别(例如LGAD传感器或3D传感器)上获得高分辨率性能。最近获得了20 ps的固有传感器时间分辨率。传感器侧的性能不断提高,要求在前端电子方面进行足够的开发,现在它有可能成为跟踪或顶点检测系统中的性能瓶颈。本文旨在分析典型使用的前端电路的最终性能,即反式放大器,考虑到不同可能的电路配置。将提供对传感器读数中的可取操作模式进行定时测量的证据。
Detectors based on pixels with timing capabilities are gaining increasing importance in the last years. Next-to-come high-energy physics experiments at colliders requires the use of time information in tracking, due to the increasing levels of track densities in the foreseen experimental conditions. Various different developments are ongoing on solid state sensors to gain high-resolution performance at the sensor level, as for example LGAD sensors or 3D sensors. Intrinsic sensor time resolution around 20 ps have been recently obtained. The increasing performance on the sensor side strongly demands an adequate development on the front-end electronics side, which now risks to become the performance bottle-neck in a tracking or vertex-detecting system. This paper aims to analyse the ultimate possible performance in timing of a typically-used front-end circuit, the Trans-Impedance Amplifier, considering different possible circuit configurations. Evidence to the preferable modes of operation in sensor read-out for timing measurement will be given.
