– DFE permits use of low -frequency de-emphasis at TX resulting in a larger received signal envelope, smaller signal/crosstalk ratio. – System capable of employing continuous adaptive …

In this paper we introduce an enhanced Decision Feedback Equalizer (DFE), based on the use of a feedforward neural network trained with the Discriminative Least Squares (DLS) algorithm.

Basic block diagram of a direct DFE. A quarter-rate sampling receiver with a 2-tap decision feedback equalizer (DFE) is implemented in 90-nm CMOS technology for low-power I/O links. …

These techniques help to compensate for post-cursor and pre-cursor ISI arising from the spread of a single pulse over time. The high level block diagram of a typical DFE is shown in Fig. 1.

Decision Feedback Equalizer (DFE) [1] is widely used in the high-speed packaging system as a part of receiver for recovering the signal from the distortion by the inter-symbol interference …

Basic idea of DFE. In the previous lectures, linear equalizers and their adaptive implementations have been studied. Linear MMSE equalizer in stochastic gradient (=LMS) adaptive …

The ADRV904x device runs an initial calibration on the SERDES PHY block to determine the appropriate settings for the CTLE and DFE block by adjusting parameters like the internal …
