摘要

研究了触发器亚稳态对连续电子束加速器(CEBAF) CLAS探测器流水线触发器的影响。研究发现，最新的ECL(发射极耦合逻辑)触发器(ECLinPS)在解决亚稳态问题上比老系列要快得多。这将允许它们在具有异步输入的系统中使用，而无需额外的同步触发器阶段。

Asynchronous inputs and flip-flop metastability in the CLAS trigger at CEBAF

The impact of flip-flop metastability on the pipelined trigger for the CLAS detector at CEBAF (Continuous Electron Beam Accelerator Facility) has been studied. It is found that the newest ECL (emitter coupled logic) flip-flops (ECLinPS) are much faster than older families at resolving the metastable condition. This will allow their use in systems with asynchronous inputs without an extra stage of synchronizing flip-flops.<>
