Title

Metamaterial-Based Gigahertz Common-Mode Filters for 10-Gbit/s and 25-Gbit/s Differential Signaling

Speaker

Miroslav Pajovic

Abstract

In addition to the desired differential signals, the undesired and EMI/SI harmful common-mode noise can propagate along differential signal lines at PCBs and IC Packages. To suppress critical common-mode at gigahertz frequencies without degrading quality of the differential signals, the gigahertz common-mode filter structures with Metamaterial properties are proposed herein. These designs are directed to compact-size electromagnetic band gap (EBG) structures suitable for placement in multilayer PCBs, individual IC chip packages, or in optical transceiver modules. The filters provide common-mode suppression at 10-Gbit/s and 25-Gbit/s differential signal lines at the EMI-critical frequencies, 10.3 GHz, 20.6 GHz, and 25 GHz, where common-mode noise can be highly problematic.

What We Will Talk About?

  • Objectives (EMI and SI issues associated with Common-Mode noise at PCB differential signal lines)
  • The relationship between Common-Mode Currents and EMI Emissions
  • Fundamentals of Metamaterial Structures
  • Metamaterial-Based (or EBG) CM Filters for 10-Gbit/s- and 25-Gbit/s-Based Differential Signaling
  • The example of other Metamaterial application - Metamaterial-based antenna
