A decision feedback circuit can include L N-tap decision feedback equalizer (DFE) branches. The L N-tap DFE branches can include K unrolled DFE branches, and L−K unfolded DFE branches. Each DFE branch can include a pre-computation stage configured to generate a set of tap-adjusted inputs, each tap-adjusted input corresponding to a possible value for at least one previous output of the same DFE branch. Each unrolled DFE branch can include a multiplexer circuit having selection lines for selecting from the set of tap-adjusted inputs for the unrolled DFE branch, the selection lines being connected to outputs of other DFE branches. Each unfolded DFE branch can include a multiplexer circuit configured to select at least one output from the set of tap-adjusted inputs based on tap-adjusted inputs from other DFE branches."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pipeline multiplexer loop architecture for decision feedback equalizer circuits","description":"Circuits, devices, methods for decision feedback equalization are described.
