【摘要】 本文设计了一款具有高灵活性的时间投影室(TPC)通用读出ASIC:GERO-NSP。GERO集成了16通道,可工作在不同的采样频率(高至100MSPS),提供可配置的(32个存储单元至1024个存储单元)大存储深度,并在片上实现数字化及串行化输出,灵活的工作模式可以满足不同的应用需求。芯片基于180nmCMOS工艺制造。本文将对第一版芯片的设计及测试结果进行说明,并对改进的第二版芯片做简要介绍。更多还原

【Abstract】 The paper presents a prototype ASIC(GERO-NSP): which is aimed to provide generic readout solution for the Time Projection Chambers(TPC). The 16-channel GERO would provide high sampling frequency, configurable storage depth, and digitization of data to meet various needs in different experiments. GERO was fabricated in 0.18 um CMOS process. The circuit design and test results of the first prototype will be discussed as well as the improvements made on the new version.更多还原
