Signaling Technique Using Inverse Exponential Function for High-Speed On-Chip Interconnects

Signaling Technique Using Inverse Exponential Function for High-Speed On-Chip Interconnects

Peer-reviewed article not indexed in WoS or Scopus

In modern digital systems where advanced miniaturization is used, on-chip interconnects are becoming more incompatible with existing signaling methods to overcome signal distortion caused by natural low-pass effect of transmission lines. Current requirements for signal pre-emphasis driver at transceiver side are logically similar to the general requirements for low-power voltage digital systems. High efficiency of signal pre-emphasis together with a minimum voltage swing during signal emphasizing and still lower power dissipation are the main features of modern signaling methods. In this paper a novel pulse shaping method based on the use of an inverse exponential function that has smaller distortion than conventional raised-cosine pulse is introduced together with advanced channel modeling. Thus, a robust pulse pre-emphasis method using combination of amplitude emphasis and time-domain emphasis is proposed. Analysis clearly shows that proposed pulse shaping method due to the spectral efficiency can increase the transmission bandwidth of low cost wire channel.
