摘要:

ATLAS液氩量热计第一阶段升级中,前端光学数据传输需要串行化ASIC和VCSEL驱动ASIC。基准ASIC是串行器LOCx 2和VCSEL驱动器LOCld,采用0.25 μm硅蓝宝石(SoS)CMOS技术设计,功耗分别为843 mW和320 mW。基于130 nm CMOS工艺,我们设计了两个引脚到引脚兼容的备份ASIC,LOCx 2 -130和LOCld-130。它们的功耗比同类产品低得多,而其他性能,如延迟,数据速率和辐射耐受性,满足第一阶段升级的要求。我们提出了LOCx 2 -130和LOCld-130的设计。最后给出了LOCx 2 -130的测试结果。

英文摘要:

A serializer ASIC and a VCSEL driver ASIC are needed for the front-end optical data transmission in the ATLAS liquid argon calorimeter readout phase-I upgrade. The baseline ASICs are the serializer LOCx2 and the VCSEL driver LOCld, designed in a 0.25-μm Silicon-on-Sapphire (SoS) CMOS technology and consumed 843 mW and 320 mW, respectively. Based on a 130-nm CMOS technology, we design two pin-to-pin-compatible backup ASICs, LOCx2-130 and LOCld-130. Their power consumptions are much lower then of their counterparts, whereas other performance, such as the latency, data rate, and radiation tolerance, meet the phase-I upgrade requirements. We present the design of LOCx2-130 and LOCld-130. The test results of LOCx2-130 are also presented.
