介绍了采用0.25 μ mCMOS工艺实现的ABCN-25读出芯片的设计和性能。前端设计已针对ATLAS内部探测器升级中预见的2.5 cm短硅条进行了优化。读出结构的核心包括二进制前端、两级数据缓冲、数据压缩和数据串行化电路，并且类似于目前ATLAS SCT检测器中使用的ABCD 3 T芯片的结构。为了保证所需的抗辐射能力，采用了版图加固技术，并增加了单粒子翻转检测和校正电路。该设计包括片上电源管理电路，包括两种类型的并联稳压器和一个串行稳压器。该电路使ABCN-25芯片与SuperLHC环境中内部跟踪器配电系统领域的最新发展兼容，特别是与探测器模块的串行供电兼容。该芯片已在0.25 μ mCMOS工艺上实现，并获得了完整的功能。模拟和数字电路的关键设计方面和性能将被介绍和讨论。
We present the design and performance of the ABCN-25 readout chip implemented in 0.25 μm CMOS technology. The front-end design has been optimized for the short, 2.5 cm, silicon strips foreseen in the upgrade of the ATLAS Inner Detector. The core of the readout architecture includes binary front-end, two levels of data buffering, data compression and data serializing circuitry, and is similar to the architecture of the ABCD3T chip used in the present ATLAS SCT detector. In order to ensure required radiation hardness the hardening by layout technique has been used and SEU detection and correction circuitry have been added. The design includes on-chip power management circuitry comprising two types of shunt regulators and a serial regulator. This circuitry makes the ABCN-25 chip compatible with recent developments in the area of power distribution systems for the inner trackers in the SuperLHC environment and in particular with serial powering of the detector modules. The chip has been fabricated in 0.25 μm CMOS technology and full functionality has been obtained. The critical design aspects and performance of the analog and digital circuits will be presented and discussed.
