How to design differential pairs in PCB transmission lines

A pair of lines can be modeled as shown on this image:

We will assume in this example that both of the lines of the pair are identical and uniform, and that they have the same separation from each other along the entire length of the line. These are precisely the characteristics of a pair of lines to be designated as a differential pair.

This eBook will:

  • Give you the keys to design better differential pairs
  • Explain differential and common mode signals, and
  • Offer a detailed analysis in terms of line inductances and capacitances

  • Odd and even modes
  • Differential signaling analysis
