摘要
随着数据率的提高和传输距离的增大,接收器的性能要求不断提升。而高速长距离下码间干扰问题已经很严重,必须使用均衡技术。均衡技术是高速收发器最大的设计重点和难点,也是现阶段Gbps数据率收发器的研究和设计热点。详细介绍了各种均衡技术并对之做了比较。
The length and the speed of transmission are increasing. So the capability of receiver must be improved. And the near end cross talk in the long - distance is very obvious. So the equalizer used. The equalizer is an important part of high- rate receivers. And It＇ s also a hot point of the of Gbps - ratio receivers. In this paper many kinds of equalizers will be introduced and will comparison of them.
