用于快速像素传感器的高分辨率定时电子器件

High-resolution timing electronics for fast pixel sensors

Adriano Lai, Gian Matteo Cossu

摘要:

基于具有定时能力的像素的检测器在过去几年中变得越来越重要。由于在可预见的实验条件下轨道密度的增加,未来在对撞机上进行的高能物理实验需要在跟踪中使用时间信息。固态传感器正在进行各种不同的开发,以获得传感器级别的高分辨率性能,例如LGAD传感器或3D传感器。最近获得了约20 ps的固有传感器时间分辨率。传感器端性能的不断提高强烈要求前端电子设备端进行充分的开发,这可能会成为跟踪或顶点检测系统的性能瓶颈。本文旨在分析一种典型的前端电路,跨阻放大器,考虑不同的可能的电路配置的最终可能的性能。将给出用于定时测量的传感器读出的优选操作模式的证据。

英文摘要:

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.
