ABSTRACT:
The invention relates to a device comprising an integrated coil L on a substrate, which coil L includes a first conductor track (1) in the form of a spiral having windings (2, 3), with an outer end (6) of the first track (1) being situated on an outside of the spiral, and an inner end (7) of the first track (1) being situated on an inside of the spiral, and said coil L comprising a conductive cross-strip (10) which is connected to the inner end (7) and continues to the outside of the spiral, so that the cross-strip (10) forms a crossing (11) with a winding (3) in the spiral. A problem with such a coil L is that the crossing (11) of the cross-strip (10) and the first conductor track (1) yields a stray capacitance which adversely affects the frequency behavior of the device. In accordance with the invention, the device is characterized in that a compensation-conductor track (21) is provided which makes electric contact (31) with a first winding (2), and which demonstrates an overlap with a winding (3) adjacent to the first winding (2). The overlap between the compensation-conductor track (21) and a winding (3) forms a compensation capacitance. The effect of the stray capacitance of the crossing (11) on the frequency behavior of the coil L is compensated for by the compensation capacitance.
