Simulation results of mutual coupling for inductors with:
  • Half-marking (L-05B)
  • Full-marking (L-07C)
  • No-marking (L-14C)


(1) Half-marked inductors L-05B Series

L-05B Series (0201) Half Marked Inductor structure

Mutual coupling(S31) with different spacing schemes

Mutual coupling(S41) for different spacing schemes

Mutual coupling(S31) for different orientations

Mutual coupling(S41) for different orientations

Text Box: *The space between half-marked inductors is 4 mils

(2)Fully Marked inductors L-07C Series

L-07C Series (0402) Fully Marked Inductor structure

Mutual coupling(S31) for different spacing schemes

Mutual coupling(S41) for different spacing schemes

 

Mutual coupling(S31) for different orientations

Mutual coupling(S41) for different orientations

(3) L-14C Series (0603) No-Marking Inductor structure

 

L-14C Series (0603) No Marking Inductor structure

Mutual coupling(S31) for different orientations

 

Mutual coupling(S41) for different orientations

Text Box: Summary:
  • The Mutual coupling of the half-marked inductors, with smaller inductor loop, is lower than that of full-marked and no-marking inductors.
  • Mutual coupling of half-marking inductors is higher when they’re placed at opposite orientations.
