HYBRID LOOP UNROLLED DECISION FEEDBACK EQUALIZER ARCHITECTURE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17736802 titled 'HYBRID LOOP UNROLLED DECISION FEEDBACK EQUALIZER ARCHITECTURE

Simplified Explanation

The patent application describes a keeper device used in a hybrid loop unrolled DFE circuit.

  • The keeper device selectively outputs signals from equalizers based on the previous bit value.
  • Equalizers corresponding to different bit possibilities are disabled in the circuit.
  • This saves power when the DFE technique is not used, as only a portion of the equalizers are powered.


Original Abstract Submitted

A keeper device is used in a hybrid loop unrolled DFE circuit to selectively output signals from equalizers corresponding to a specific possibility of the values of the previous bit (e.g., logical high or logical low) when DFE technique is not used. Those equalizers corresponding to possibilities other than the specific possibility of the values of the previous bit are disabled in the hybrid loop unrolled DFE circuit. As such, the hybrid loop unrolled DFE circuit saves power when the DFE technique is not used since only a portion of the total equalizers in the hybrid loop unrolled DFE circuit are powered.
