Embodiments can provide direct feedback for DFE correction in a manner that is effective in high-speed data channels, while manifesting less latency, power consumption, and/or area than conventional DFE implementations. In some implementations, in each clock cycle (e.g., Tn), implementations can select (e.g., using a multiplexer) between a positive reference signal and a negative reference signal (e.g., both reference signals generated according to an inter-symbol interference magnitude for a data channel) according to a decision feedback signal from a previous clock cycle (Tn−1). The selected reference signal can be compared (e.g., in the same clock cycle Tn, using a comparator) with an input data signal to generated an updated decision feedback signal for a next clock cycle (e.g., Tn+1)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fast direct feedback circuit for decision feedback equalization correction","description":"Embodiments include systems and methods for providing fast direct feedback to correct decision feedback equalization (DFE) in receiver circuits.
