  • Circuit for reducing distortion of class D amplifier
    Patent number: 7382188
    Abstract: A class-D switching amplifier is disclosed. The class-D switching amplifier includes two control circuits, a load, and six switching devices. The load is coupled to the six switching devices. The first and the second control circuits provide a first and a second PWM pulse respectively. Each of the first and second switching devices has a first terminal coupled to a first voltage level, a second terminal coupled to the load, and a control terminal coupled to the first control circuit. Each of the third, fourth, fifth, and sixth switching devices has a first terminal coupled to a second voltage level, and a second terminal coupled to the load. The control terminals of the third and fourth switching devices are coupled to the first control circuit. The control terminals of the fifth and sixth switching devices are coupled to the second control circuit.
