Abstract: A device includes a filter circuit having both a transformer and a notch filter. The notch filter is formed via capacitive cross-coupling of windings of the transformer. The transformer includes a first winding with an input terminal and an output terminal and a second winding with an input terminal and an output terminal. The notch filter is formed by coupling a first capacitor between the input terminal of the first winding and the output terminal of the second winding, and by coupling a second capacitor between the output terminal of the first winding and the input terminal of the second winding.
