FILTER CIRCUIT

摘要

A filter circuit (1) is disclosed for filtering out an input voltage (U_b) applied to an input terminal (E) in order to generate a filtered output voltage (U_a) at an output terminal (A). The filter circuit (1) has at least one regulation element (V₁) with a regulation terminal (RG₁), and a regulation section (RS₁) with a regulation section input (RE₁) connected to the input terminal (E) and a regulation section output (RA₁). The filter circuit (1) further has a capacitor (C₁) connected to the regulation terminal (RG₁) and a resistor (R₁) which connects the regulation section input (RE₁) to the regulation terminal (RG₁).
