Abstract:
    A class D amplifier includes: an amplifier circuit in which a high side switching element and a low side switching element are connected in series between power sources; a high side gate driving circuit for driving a high side gate of the high side switching element; and a low side gate driving circuit for driving a low side gate of the low side switching element. In the class D amplifier, the high side gate driving circuit is configured so that a charging time of the high side gate is shorter than a discharging time of the high side gate, and the low side gate driving circuit is configured so that a charging time of the low side gate is longer than a discharging time of the low side gate.
