| 摘要 |
The invention relates to a device for a microcircuit electronic unit, comprising at least two essentially parallel conducting layers (200-1, 200-2), insulated from each other, a winding of a conducting track (210) with at least two turns formed in a first layer (200- 2). A first conducting track (215-2) formed in the first layer is electrically connected to one of the ends of the winding. A second conducting track is formed in the second layer (200-1), a part of said second conducting track (215-11) being essentially aligned with the first track in a normal to the layers, such that a part of the first and second conducting tracks form a first capacitive coupling between the first and the second layers. A third conducting track (220-2) is formed in the first layer (200-2). A fourth conducting track is formed in the second layer (200-1), a part of said fourth conducting track (220-11) being essentially aligned with the third track in a normal to the layers, such that a part of the third and fourth conducting tracks form a second capacitive coupling between the first and second layers. One of the second and fourth tracks (215-12) runs from one side to the other of the turns. |
