A Systematic Equalizer Design Technique Using Backward Directional Design

Abstract

This paper presents a systematic equalizer design methodology using a backward directional design (BDD). The proposed design method includes pre-emphasis and crosstalk cancellation design and offers a proper waveform solution for transmitters (TX). Since it is driven by a user-defined specification, it avoids over/under design, reducing wasted power. Furthermore, the proposed design procedure is summarized in systematic algorithms and provides an automated design environment. The procedure has been tested for various line conditions to verify the algorithms. The result shows that the proposed method successfully designs equalizers to within a 2.4% error.
