Classification: CPC H | IPC H

Claim 0:
1. A circuit comprising:
a first input node;
a second input node;
a bias voltage node coupled to a direct-current (DC) voltage value; and
a notch filter, the notch filter comprising:
a filter transformer including a first winding and a second winding, and
a capacitor bank including a first capacitor and a second capacitor,

wherein a positive-polarity terminal of the first winding is coupled to the first input node and a negative-polarity terminal of the first winding is coupled to a first terminal of the first capacitor;
wherein a positive-polarity terminal of the second winding is coupled to the second input node and a negative-polarity terminal of the second winding is coupled to a first terminal of the second capacitor, and
wherein a second terminal of the first capacitor and a second terminal of the second capacitor are coupled to the bias voltage node.
