Abstract: A transient noise reduction filter comprises a cable including one or more twisted pairs of conductors and one or more common mode chokes (CMCs). The one or more CMCs a formed from respective pluralities of turns of the cable. Each of the CMCs may be a magnetic CMC wherein the plurality of turns of the cable are wrapped around a magnetic core, or an air-core CMC wherein the plurality of turns of the cable are not wrapped around a magnetic core but are instead disposed around a non-magnetic material (such as air)

Abstract: A full-bridge class-D amplifier circuit comprises first through fourth power devices. First conduction terminals of the first and third power devices are coupled to a first power supply voltage, and second conduction terminals of the second and fourth power devices are coupled to a second power supply voltage. A second conduction terminal of the first power device and a first conduction terminal of the second power device are coupled to a first amplifier output. A second conduction terminal of the third power device and a first conduction terminal of the fourth power device are coupled to a second amplifier output. Left and right driver devices respectively disposed adjacent to left and right sides of the first power device have outputs respectively coupled to left and right control terminals respectively disposed on the left and right sides of the first power device.
