我们介绍了采用CMOS0.25μm工艺实现的ABCN-25前端芯片的测试结果，该芯片针对用于升级ATLAS内部探测器的2.5 cm短硅带进行了优化。获得了读出部分的全部功能、模拟前端的预期性能和功率控制电路的运行情况。考虑到功耗的最小化来评估性能，因为升级检测器可以包含多达7000万个通道。利用该芯片可以对未来的跟踪器探测器进行不同功率分配方案的系统测试。ABCN-25ASIC现在作为ATLAS内探测器升级模块和STEST开发的原型读出芯片。
We present the test results of the ABCN-25 front end chip implemented in CMOS 0.25 μm technology and optimised for the short, 2.5 cm, silicon strips intended to be used in the upgrade of the ATLAS Inner Detector. We have obtained the full functionality of the readout part, the expected performance of the analogue front-end and the operation of the power control circuits. The performance is evaluated in view of the minimization of the power consumption, as the upgrade detector may contain up to 70 million of channels. System tests with different power distribution schemes proposed for the future tracker detectors are possible with this chip. The ABCN-25 ASIC is now serving as the prototype readout chip in the developments of the modules and staves for the upgrade of the ATLAS Inner Detector.
