摘　　要：并串转换电路作为PCI Express物理层(PHY)发送端的重要模块之一,将来自PCS(Physical codingsublayer)子层的10bit并行数据转换成1bit串行数据.该文提出并实现了一种高性能并串转换电路,采用0.18μm工艺版图实现,反标寄生参数后使用spice进行仿真,仿真结果证明该电路可在1.0 GHz^1.5GHz稳定工作,其最高数据传输速度达到3Gbps,完全达到了预期效果.As an important part of the PHY（Physical Layer） in PCI Express, the high Speed Serializer transmits the 10bit parallel data into 1bit serial data. A new type of serializer with high performance for PCI Express is presented in this paper, which reaches the bandwidth of 2.5Gbps, realized with full CMOS technics, and is compatible with the features of PCI Express. When designed with 0.18μm CMOS technology, extracting parameters from the layout for SPICE simulation, it indicates that the circuit works nice with the acceptable frequency ranges from 1.0GHz to 1.5GHz and the bandwith up to 3Gbps.
