Integrated resonant circuit with temperature compensated quality factor |
摘要 |
A filter (13) for providing temperature compensation for the quality factor thereof comprises transconductance amplifiers (23 and 24) in a gyrator configuration coupled between an input node (21) and an output node (22). A parallel capacitor (25) is coupled between the input node (21) and a supply voltage, and a parallel resistor (26) is coupled between the input node (21) and the supply voltage. A series capacitor (27) is coupled to the output node (22), and a series resistor (28) is coupled between the second capacitor (27) and the supply voltage.
