Adaptation circuitry and methods for decision feedback equalizers |
摘要 |
Decision feedback equalizer (DFE) circuitry bases determination of the coefficients that are used in its various taps on the algebraic sign of the current value of an error signal and prior serial data signal values output by the DFE circuitry. Use of such algebraic sign information (rather than full error signal values) greatly simplifies the circuitry needed to determine the tap coefficients. The DFE circuitry can be adaptive, i.e., such that it automatically adjusts the tap coefficients for changing serial data signal transmission conditions. |
