Reference voltage generators for reducing and/or eliminating termination mismatch

摘要

A system including a plurality of transmission lines, a transmitter outputting respective signals to each of the plurality of transmission lines, a receiver receiving each of the plurality of signals via respective transmission lines, the receiver including a connection path connected to a termination voltage, a plurality of termination circuits distributed along the connection path, each termination circuit receiving a unique termination voltage from the connection path, receiving a respective signal and outputting a terminated input signal, a reference voltage generator including multiple reference voltage generator units connected to a common voltage, each reference voltage generator unit uniquely receiving at least one unique termination voltage and outputting a reference voltage, and a plurality of data input buffers receiving respective signals and an appropriate reference voltage of the multiple reference voltages output from the reference voltage generator.
