摘要：

In this paper, we present an adaptive decision feedback equalizer (ADFE) for multi-Gbps serial links utilizing a fix-step error signal extracted from cross-points of received data symbols. The extracted signal is generated based on the violation of received data symbols with minimum detection requirements at the signal-detection unit. The iterations of the adaptation process search for the optimum feedback tap coefficients to maximize the data eye-opening and minimize the adaptation convergence time. The validity of the proposed architecture is proved to utilize a serial link designed in an IBM 130 nm 1.2V CMOS technology. The data link with variable channel lengths is analyzed using Specter from Cadence Design Systems with BSIM4 device models.
