APPARATUSES AND METHODS FOR INPUT BUFFER DATA FEEDBACK EQUALIZATION CIRCUITS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240161791 titled 'APPARATUSES AND METHODS FOR INPUT BUFFER DATA FEEDBACK EQUALIZATION CIRCUITS

Simplified Explanation

The patent application describes apparatuses, systems, and methods for input buffer data feedback equalization (DFE). The DFE circuit in the input buffer adjusts the threshold voltage based on a previously latched data bit. The DFE circuit includes multiple DFE legs coupled in parallel to a node of the input buffer, each selectively activated by a DFE code. Each DFE leg includes a capacitance (e.g., a field effect transistor) coupled to the node based on the previously latched data bit, and may also include a transistor coupled to a bias voltage stable across PVT variations.

Original Abstract Submitted

apparatuses, systems, and methods for input buffer data feedback equalization (dfe). an input buffer includes a dfe circuit which adjusts a threshold voltage of the input buffer based on a previously latched data bit. the dfe circuit includes a number of dfe legs coupled in parallel to a node of the input buffer. each dfe leg is selectively activated by a dfe code. each dfe leg includes a capacitance (e.g., a field effect transistor) which is coupled to the node in an active leg based on the previously latched data bit. the previously latched data bit may also be used to generate a reset signal which couples the capacitors to ground. each dfe leg may also include a transistor coupled to a bias voltage, which is stable across a range of pvt variations.
