Abstract

Die Schaltkreis-Anordnung weist eine Mehrzahl von Filterstufen einer Filterbank auf sowie eine Mehrzahl von Resonator-Schaltkreisen. Ferner enthält die Schaltkreis-Anordnung einen Resonator-Steuer-Schaltkreis zum Steuern oder Regeln der Güte der Resonator-Schaltkreise, wobei der Resonator-Steuer-Schaltkreis derart eingerichtet ist, dass er die Güte mindestens eines Resonator-Schaltkreises abhängig von der Amplitude des Eingabesignals und/oder des Ausgabesignals des Resonator-Schaltkreises steuert oder regelt.The circuit arrangement comprises a plurality of filter stages of a filter bank as well as a plurality of resonator circuits. Further, the circuit arrangement includes a resonator control circuit for controlling the quality of the resonator circuits, wherein the resonator control circuit is arranged to match the quality of at least one resonator circuit depending on the amplitude of the input signal and / or the output signal of the resonator circuit controls or regulates.
