本文介绍了ATLAS液氩量热计触发器升级中编码器集成电路的设计和测试结果。编码器实现了一个低延迟和低开销的线路代码，称为LOCic。编码器工作在320 MHz，延迟不超过21 ns。编码器的开销为14.3%。该编码器是发射机ASIC LOCx 2的重要模块，采用商用0.25 μ mSilicon-on-Sapphire CMOS工艺进行原型设计，采用100引脚QFN封装。
In this paper, we present the design and test results of an encoder integrated circuit for the ATLAS Liquid Argon Calorimeter trigger upgrade. The encoder implements a low-latency and low-overhead line code called LOCic. The encoder operates at 320 MHz with a latency of no greater than 21 ns. The overhead of the encoder is 14.3%. The encoder is an important block of the transmitter ASIC LOCx2, which is prototyped with a commercial 0.25 μm Silicon-on-Sapphire CMOS technology and packaged in a 100-pin QFN package.
