摘要
随着航空电子系统模块化、集成化的程度越来越高,采用ARINC818协议使新一代航空电子系统能够高速、实时地传输大容量数字视频信息,其对传输的信号质量要求更高。基于ARINC818协议的高速信号传输系统,设计了新型连续时间线性均衡器(CTLE)。在传统CTLE的基础上,将折叠式共源共栅型拓扑结构叠加在传统一级CTLE的输出端,形成二级结构,可以增加高频增益,达到信道补偿的目的。仿真结果显示在2.125 Gibit/s的速率下,二级均衡器结构有良好的补偿能力,均衡后的眼图水平张开度达到0.87UI。
With the increasing degree of modularization and integration of avionic systems,the ARINC 818 standard is used to make the new-generation avionic system transmit large-capacity digital video information at high speed in real time,which requires higher quality for the transmitted signal.A new Continuous Time Linear Equalizer(CTLE)is designed based on the ARINC 818 protocol for high-speed signal transmission systems.On the basis of the traditional CTLE,the folded cascode topology structure is imposed on the output of the conventional first-order CTLE to form a secondary structure,which can increase the high-frequency gain and achieve the purpose of channel compensation.The simulation results show that:at the rate of 2.125 Gibit/s,the two-level equalizer structure has good compensation ability,and the horizontal opening degree of equalized eye reaches 0.87UI.
