Abstract :
An adaptive decision-feedback equalizer (DFE) that uses an infinite impulse response (IIR) feedback equalizer is presented. The target application is 100Base-TX Ethernet. Initially, a simple single pole feedback equalizer is considered. Then pole/zero feedback equalizers are considered. Simulation results are presented that compare the performance of these architectures.
