DRIVER CIRCUIT FOR A POWER STAGE OF A CLASS-D AMPLIFIER

Embodiments of a driver circuit for a power stage of a class-D amplifier and a class-D amplifier are described. In one embodiment, a driver circuit for a power stage of a class-D amplifier includes serially connected transistor devices connected to a gate terminal of a power transistor of the power stage of the class-D amplifier, a voltage generator connected between a gate terminal of a first transistor device of the serially connected transistor devices and a source terminal of the power transistor, and a current multiplier connected between the gate terminal of the power transistor and one of a source terminal and a drain terminal of the first transistor device. The current multiplier is configured to produce an output current that is proportional to a current at the one of the source terminal and the drain terminal of the first transistor device.
