Abstract

Eye diagram used in a lot of radio and telecommunication application, but it can also be used in digital signal integrity. This kind of analysis is a common indicator of performance in digital transmission systems. As integration density and data rates increase, dispersive losses, reflections and crosstalk can severely degrade signal integrity. Fortunately, these effects are linear processes. Accordingly, simple, on-chip signal processing techniques can compensate for them. In this paper we introduce an approach to improve eye diagram for data transmission that indicate the signal strength by using adaptive Decision Feedback Equalizer (DFE) in receiver circuits of digital system. The simulation results are presented to validate the efficiency of the proposed method.
