摘要:

我们提出了一个可编程的时间对准方案中使用的ASIC的ATLAS前向μ子触发器的发展。该方案利用再生时钟与可编程的相位,以补偿不同的检测器走线长度引入的定时偏移。设计中使用的每个ASIC具有104个输入通道,延迟补偿电路为每个通道提供约3 ns的步长和25 ns的全范围。该计划包括多数逻辑抑制单粒子效应的详细实施。该方案是灵活的,完全综合。该方法适用于具有类似相移要求的其他应用。此外,该设计是资源有效的,并且适合于具有大量通道的成本有效的数字实现。

英文摘要:

We present a programmable time alignment scheme used in an ASIC for the ATLAS forward muon trigger development. The scheme utilizes regenerated clocks with programmable phases to compensate for the timing offsets introduced by different detector trace lengths. Each ASIC used in the design has 104 input channels with delay compensation circuitry providing steps of ~ 3 ns and a full range of 25 ns for each channel. Detailed implementation of the scheme including majority logic to suppress single-event effects is presented. The scheme is flexible and fully synthesizable. The approach is adaptable to other applications with similar phase shifting requirements. In addition, the design is resource efficient and is suitable for cost-effective digital implementation with a large number of channels.
