Abstract (en)

[origin: WO2006081939A2] A filter circuit (1) is disclosed for filtering out an input voltage (U<SUB>b</SUB>) applied to an input terminal (E) in order to generate a filtered output voltage (U<SUB>a</SUB>) at an output terminal (A). The filter circuit (1) has at least one regulation element (V<SUB>1</SUB>) with a regulation terminal (RG<SUB>1</SUB>), and a regulation section (RS<SUB>1</SUB>) with a regulation section input (RE<SUB>1</SUB>) connected to the input terminal (E) and a regulation section output (RA<SUB>1</SUB>). The filter circuit (1) further has a capacitor (C<SUB>1</SUB>) connected to the regulation terminal (RG<SUB>1</SUB>) and a resistor (R<SUB>1</SUB>) which connects the regulation section input (RE<SUB>1</SUB>) to the regulation terminal (RG<SUB>1</SUB>).
