摘要

A continuous-time linear equalizer (CTLE) for high-speed serial link is presented whose adaptive boosting gain is obtained with the data and edge values sampled by clock and data recovery circuit. The input offset of the serial link receiver is estimated by the data and edge values as well and cancelled by the CTLE. The adaptation of the CTLE boosting gain is immune to the phase error of the clock and data recovery sampling clock, and the cancellation of the input offset is independent of the boosting gain adaptation. The performance of the proposed adaptive CTLE has been evaluated by applying it to a 5-Gb/s serial link receiver implemented in a 65-nm CMOS technology.
