我们介绍了ABCN前端芯片的设计，该芯片采用CMOS0.25μm工艺实现，并针对短硅带探测器进行了优化，预计将在ATLAS Silicon Tracker升级中使用。该项目的一个主要目标是开发一种ASIC，它具有在SLHC环境中以经济高效和经过验证的技术读出短硅带所需的全部功能。设计工作的重点是优化前端电路的噪声和功率性能，以实现低探测器电容，将数字块中的功耗降至最低，以及与正在为未来的跟踪器探测器开发的新电源分配方案的兼容性。文中讨论了该芯片的体系结构以及关键和新颖的设计方面。ABCN ASIC将作为ATLAS硅跟踪器升级的传感器和模块开发的广泛计划中的基本测试工具。
We present the design of the ABCN front-end chip implemented in a CMOS 0.25 μm technology and optimized for short silicon strip detectors as foreseen for the ATLAS Silicon Tracker Upgrade. A primary aim of this project is to develop an ASIC with full functionality required for readout of short silicon strips in the SLHC environment in a cost-effective and proven technology. Design efforts have been focused on optimizing noise and power performance of the front-end circuit for low detector capacitance, minimizing power consumption in digital blocks and on compatibility with new power distribution schemes being developed for future tracker detectors. The architecture of the chip as well as critical and novel design aspects are discussed in the paper. The ABCN ASIC will serve as a basic test vehicle in an extensive program on development of sensors and modules for the ATLAS Silicon Tracker Upgrade.
