摘要：A filter (13) for providing temperature compensation for the quality factorthereof comprises transconductance amplifiers (23 and 24) in a gyrator configurationcoupled between an input node (21) and an output node (22). A parallel capacitor (25) iscoupled between the input node (21) and a supply voltage, and a parallel resistor (26) iscoupled between the input node (21) and the supply voltage. A series capacitor (27) iscoupled to the output node (22), and a series resistor (28) is coupled between the secondcapacitor (27) and the supply voltage.
