Comparison of NRZ and 4-PAM Coding for High-Speed VLSI Data Transmission

Abstract:

As the Required Data Rate for VLSI System Communication Increases, Channel Bandwidthlimitation Becomes a Crucial Problem as High-Frequency Channel Loss Degrades the Transmission Performance.In this Paper, we Compare Non-Return-to-Zero (NRZ) Binary and 4-PAM (pulse Amplitudemodulation) Coding Techniques for High-Speed Data Transmission by Fabricating a Test Board of a Microstripline. by Extracting the Micro-Strip Line Parameters, we Carry out Co-Simulations to Evaluate Spectrallyefficient Coding for High-Speed Data Transmission.We Consider the Conditions for which 4-Pamsignaling Provides an Advantage over NRZ Signaling from the Viewpoint of Channel Profiles.
