我们提出了CBC 2的设计，新版本的CMS二进制芯片ASIC的读出CMS跟踪器第二阶段升级。CBC 2采用130 nm CMOS设计，将输入通道加倍至254个，并将凸点键合到衬底上。ASIC被设计成在外部跟踪器中仪表化双层模块，其由具有对准的微带的两个重叠的硅传感器组成，并且结合逻辑以识别“微”形式的L1触发基元：高横向动量候选者，其通过选择两个紧密分离的微带传感器之间的相关命中而与低动量背景隔离。重合逻辑的功能，其中包括拒绝宽集群和偏移校正，以占在R-平面中的模块的位置，详细描述。
We present the design of CBC2, the new version of the CMS Binary Chip ASIC for the readout of CMS Tracker Phase-two upgrade. CBC2, designed in 130nm CMOS, doubles the input channels to 254 and will be bump-bonded to the substrate. The ASIC is designed to instrument double layer modules in the outer tracker, consisting of two overlaid silicon sensors with aligned microstrips, and incorporates the logic to identify L1 trigger primitives in the form of ``stubs'': high transverse-momentum candidates which are isolated from the low momentum background by selecting correlated hits between two closely separated microstrip sensors. The functionality of the coincidence logic, which includes rejection of wide clusters and offset correction to account for the position of the module in the R- plane, is described in detail.
