Abstract:
A monolithic semiconductor inductive component comprising:a semiconductor substrate which extends substantially in a plane;a first coil having a first axis and being formed on said substrate so that said first axis is substantially parallel to said plane;a second coil having a second axis and being formed on said substrate so that said second axis is substantially parallel to said plane, said second coil being electricaly connected in series with said first coil so that electrical current advances in substantially opposing directions along said first and second axes through said first and second coils, respectively; anda coil core formed on said substrate and formed from a magnetic material and configured so that a substantially continuous path of magnetic material passes through said first and second coils along said first and second axes; whereinsaid first coil, said second coil, and said coil core form a monolithic inductor having magnetic flux lines guided away front said substrate.
