Abstract:
Some embodiments include apparatus having multiple samplers in a decision feedback equalizer (DFE). The multiple samplers include at least two samplers and are configured to be activated in a first mode of the DFE to receive first input information from a summing circuit. At least one of the samplers is configured to be deactivated in a second mode of the DFE. At least one of the samplers is configured to be activated in the second mode of the DFE to receive second input information from the summing circuit.
