Formula

The impedance values for edge coupled striplines are calculated using industry-standard electromagnetic field equations. These include:

• Odd-Mode Impedance (Zₒodd): Represents the impedance of one trace when the pair carries out-of-phase signals.
• Even-Mode Impedance (Zₒeven): Represents the impedance when both traces carry in-phase signals.
• Differential Impedance (Zₒdiff): Calculated as:
  Zₒdiff = 2 × Zₒodd

These values depend on factors like:

• $W$: Trace width.
• $S$: Spacing between traces.
• $H$: Dielectric thickness.
• $\epsilon r$: Relative permittivity of the dielectric.
• $T$: Trace thickness.
