A DFE receiver with equalized VREF for multidrop single-ended signaling

In this brief, decision-feedback equalization (DFE) receiver for multidrop single-ended signaling is described. The proposed DFE receiver adopts a reference voltage having equalization information to remove channel intersymbol interference. It uses a smaller number of DFE tap elements than the conventional DFE receiver for the same level of equalization, resulting in reduced power consumption and silicon area, particularly for multi-input/output interface. The proposed DFE receiver was fabricated in a 0.13-μm CMOS process, whose evaluation results indicate a reliable operation up to 3.40-Gb/s data rate with reduced power consumption.
