AI总结:

ALFE2是为HL-LHC升级设计的ATLAS液氩量能器前端ASIC,具有四通道、可调阻抗和16位动态范围,经FETB测试表明其在增益、噪声、线性、均匀性和辐射耐受性方面均满足或大幅超越所有规格。

摘要:

ALFE2是为HL-LHC升级设计的ATLAS液氩量能器(LAr)前端ASIC。ALFE2包含四通道前置放大器和CR-(RC)2成形器,输入阻抗可调。ALFE2具有两个独立的增益输出,以提供16位动态范围覆盖和最佳分辨率。ALFE2使用基于Zynq UltraScale+ MPSoC和两个八通道16位高速ADC的前端测试板(FETB)进行特性表征。测试结果表明,ALFE2满足或大大超过了增益、噪声、线性、均匀性和辐射耐受性的所有规格。

英文摘要:

ALFE2 is an ATLAS Liquid Argon Calorimeter (LAr) Front-End ASIC designed for the HL-LHC upgrade. ALFE2 comprises four channels of pre-amplifiers and CR-(RC)2 shapers with adjustable input impedance. ALFE2 features two separate gain outputs to provide 16-bit dynamic-range coverage and an optimum resolution. ALFE2 is characterized using a Front-End Test Board (FETB) based on a Zynq UltraScale+ MPSoC and two octal-channel 16-bit high-speed ADCs. The test results indicate that ALFE2 fulfills or greatly exceeds all specifications on gain, noise, linearity, uniformity, and radiation tolerance.
