Abstract :
A 45 nm CMOS receiver based on an unclocked DFE is presented. A bi-dimensional equalization simultaneously adapts the DFE tap value and feedback delay, optimizing both the vertical and horizontal eye opening at the sampler input. Realized prototypes show error free operation at 12 Gb/s with 39 dB backplane loss. The receiver core occupies 0.1 mm2 and consumes 130 mW.
