  • Patent number: 5886394
    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.

  • Patent number: 5859607
    Abstract: In a receiver, both an A/D conversion (ADC) and a phase-split (PSF) is carried out on an input signal (R) to obtain a pair of digital signals (Xd,Yd) which are mutually phase shifted. The pair of digital signals (Xd,Yd) is processed (VSP) as a vectorial signal with a frequency-characteristic which is asymmetrical with respect to zero frequency. In order to make the receiver better suited for relatively low A/D conversion sampling frequencies (Fs), the phase-split (PSF) is carried out prior to the A/D conversion (ADC).
