Definitions

  • the invention relates to a planar, coupled coil arrangement, which, for example, in an oscillator or Bandpass can be used.
  • a planar, coupled coil arrangement which, for example, in an oscillator or Bandpass can be used.
  • it can also as a transformer, as an impedance converter, for coupling amplifier stages or serve for galvanic isolation.
  • a coil is a component that is electromagnetic Can store energy.
  • the coil is made by constructive Coil data such as length, diameter, shape, number of turns, Core material and core shape specified.
  • single or multi-layer cylindrical or ring coils uses a special ferromagnetic core in Can get rod, ring or shell shape.
  • An object of the invention is a planar, coupled Specify coil arrangement in which the disadvantages of the state of technology can be avoided.
  • the planar, coupled coil arrangement has a first coil in which a first conductor track portion the first coil is arranged in a first plane and the portion of the conductor track that completes the first coil is arranged in a second level and by an or several connections with the first conductor part electrically connected is.
  • a second coil is provided in which the conductor track is completely or partially in the second Level is arranged at which if the second coil for Part is arranged in the second plane, which is the second coil complete part of the trace in the first or arranged on a third level and by one or more Connections to the first conductor part of the second coil is electrically connected.
  • the coils are symmetrical to each other arranged and the conductor tracks of the coils to each other arranged that a coupling takes place between the coils.
  • a third coil in which the conductor track arranged entirely or in part on the third level and, if the conductor path of the third coil to Part is arranged in the third level, which is the third coil complete part of the trace in the first or the second level and is arranged by one or more Connections to the first conductor part of the third coil is electrically connected.
  • the coil connection conductor tracks for tapping the coil have through one or more connections electrically connected to the conductor track of the corresponding coil are.
  • the coils can be round. This has the advantage that an optimal coupling between the coils can be achieved can.
  • the coils can also be made square. This has the The advantage of being easy to manufacture.
  • the coils are advantageously around a circuit arranged. This saves space.
  • planar, coupled coil arrangement according to the invention is advantageously in an oscillator, in a bandpass, as Transformer, as an impedance converter, for coupling amplifier stages or usable for galvanic isolation.
  • FIG. 1 there are two coils S1 and S2, which over a resistor R1 is connected to a conductor track L1, which, for example, can have a reference potential.
  • the black areas of the coils S1 and S2 yourself in a first level.
  • the connections V1 and V2 (gray drawn) are on a second level and connect the conductor track ends A, B and A ', B' with each other.
  • the Connections between the first level and the second level at points A, B, A 'and B' can, for example, by Vias are made.
  • the coil connections of the coils S1 and S2 are labeled A1, A2 and A3.

  • the conductor track V is part of the coils S3 and S4 according to FIG. 3.
  • the coils S3 and S4 have a common connection A6, as well as a connection A5 or A4. Within this A circuit can be provided for coils. First, this has the advantage that space can be saved and secondly that to get from the circuit to terminals A4 and A5 no additional bridges to bridge the conductor tracks the coils S3 and S4 are necessary.
  • the coupling takes place in the respective one between the coils S1 and S2 Level.
  • the two coils S1 and S2 are predominantly on top of each other. While the coil S1 is mainly in the is on the first level, the coil S2 is predominantly on the second level. The first level is gray, the second Drawn level black.
  • the coil S1 has the connections A1 and A2 on. The connections A3 and A4 belong to the coil S2.
  • the coils S1 and S2 are in three-dimensional view shown.
  • the coil S2 is located directly below the coil S1.
  • connections provided in the second level (drawn in black), to bridge the gap between points A and B in the first level conductor track of the first coil S1 to serve.
  • the connections are with corresponding plated-through holes with the respective conductor tracks of the coils connected.
  • the coupling of the coils S1 and S2 takes place across the two levels. As from the 6 can be seen, the coils S1 and S2 symmetrical to each other.
  • FIG. 7 In addition to the embodiment shown in Figure 7 the fourth embodiment of the coil arrangement shown in FIG a further coil S3, which is in a third Level.
  • the coil S3 has the connections A5 and A6 on.
  • the coil S3 is also transverse to the levels 1, 2 and 3 coupled to the coils S1 and S2.

  • coil taps can be executed.
  • connecting conductor tracks C, D and E are provided with the corresponding connections A7, A8 and A9. While the turns of the coils are on the top Level (drawn in gray) are the connecting conductor tracks C, D and E and the connections between points A, B and A ', B' provided on the lower level (drawn in black). The coupling takes place here within the level.
  • the coil S1 has the connections A1 and A2, the coil S2 the connections A3, A7 and A4, and the coil S3 the connections A5 and A6
  • the connection A7 provides a center tap of the coil S2 represents the connection between points A and B of the coil S2 is provided on a third level.
  • the coil arrangement according to the invention is also optimized in that that the number of layers of metallization required are minimized in the integrated circuit.
