Abstract
In an embodiment a low-pass filter arrangement has an input terminal for receiving an input voltage, a first voltage source coupled to the input terminal, a serial connection comprising a first and a second filter diode, the serial connection being coupled to the first voltage source, wherein a connection point between the first and the second filter diode is coupled to an output terminal of the filter arrangement, and a first filter capacitor coupled between the output terminal and a filter reference potential terminal. Therein the first voltage source is adapted to provide a first adjustable forward voltage whereby the first and the second filter diodes are both biased in a forward direction.
