摘要： A sensor arrangement has a plurality of Hall sensor devices, each configured to provide a sensor voltage in response to a magnetic field intensity. A selection unit is configured to forward either of the sensor voltages in response to a selection signal. A transconductance amplifier is configured to generate a sensing current depending on a forwarded sensor voltage. A filter stage has a resistor and a filter capacitor connected in parallel in a switchable manner in response to a first switching signal. The filter stage is configured to generate a filtered voltage across the filter capacitor depending on a sensing current. A capacitive analog-to-digital converter has an input capacitor being connected to the filter capacitor in a switchable manner in response to a second switching signal. The analog-to-digital converter is configured to generate a digital sensor value based on a filtered voltage. The sensor arrangement further has a control circuit which is configured to generate the selection signal and the first and the second switching signals such that for each of the forwarded sensor voltages in a first time segment, the filtered voltage across the filter capacitor is generated, and in a second time segment, the input capacitor is connected to the filter capacitor.

摘要： An arrangement includes a transformer having a primary winding and a secondary winding, the transformer exhibiting an impedance across the primary winding, and an impedance synthesis circuit. The impedance synthesis circuit includes a transfer function element having a frequency spectrum. The transfer function element has associated a gain element and a current source controlled by the transfer function element. The impedance synthesis circuit is connected to said secondary winding, so that the transformer mirrors the impedance synthesized by the impedance synthesis circuit into the impedance across said primary winding. The primary winding is adapted to define the high voltage side of an XDSL splitter, while the impedance synthesis circuit connected to the secondary winding is inherently a low voltage circuit.
