高速串行接口接收机前端的自适应循环偏移消除

Adaptive cyclic offset cancellation for the receiver front-end of high-speed serial links
Abstract:
A receiver for a serial link. The receiver has an analog input configured to receive a received signal and includes a first front end comprising a first sampler configured to sample a signal at an input of the first front end, and a first correction circuit configured to add a first correction to the signal at the input of the first front end, the first correction including a first offset correction. The offset correction is updated by a modified sign-sign least mean squares method.
Abstract(Chinese):

串行链接的接收器。 接收器具有被配置为接收接收信号的模拟输入，并且包括第一前端，其包括被配置为在第一前端的输入端采样信号的第一采样器，以及第一校正电路，其被配置为向信号添加第一校正 在第一前端的输入处，第一校正包括第一偏移校正。 通过改进的符号最小均方法更新偏移校正。
