论文摘要
在Atlas液体氩热量读数I升级的前端光学数据传输中,需要串行器ASIC和VCSEL驱动器ASIC。基线ASIC是序列化器Locx2和VCSEL驱动器LocD,该LocD在0.25-μm硅(SOS)CMOS技术中设计,分别消耗了843 MW和320 MW。基于130 nm的CMOS技术,我们设计了两个与PIN至PIN兼容的ASIC,Locx2-130和Locld-130。它们的功耗要比同行的功率低得多,而其他性能,例如延迟,数据速率和辐射耐受性,满足了I期升级要求。我们介绍了Locx2-130和Locld-130的设计。还提出了Locx2-130的测试结果。
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.
