A circuit includes an amplifier, a pre-driver circuit, and an output circuit. The amplifier has a first input, a second input, and an output. The pre-driver circuit has an input coupled to the output of the amplifier, a first output, a second output, and a third output coupled to the second input of the amplifier. The output circuit includes a first transistor and a second transistor. The first transistor has a control terminal coupled to the first output of the pre-driver circuit; a first terminal, and a second terminal coupled to the third output of the pre-driver circuit. The second transistor has a control terminal coupled to the second output of the pre-driver circuit, a first terminal coupled to the second terminal of the first transistor, and a second terminal coupled to a reference terminal.
