Abstract
Multi-level decision feedback equalization (MDFE) is a detection technique which achieves equivalent error rate performance to fixed-delay tree search with decision feedback equalization, while using the simpler architecture of decision feedback equalization. The desired equalization target in MDFE is accommodated by a low order IIR filter, thereby suggesting that all of the forward filtering can be done with continuous-time filters. A potentially low power architecture for MDFE will be described which includes circuit considerations for the phase and gain detectors.Keywords
