Adaptive cyclic offset cancellation for the receiver front-end of high-speed serial links

摘要

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.
