A multi-stage Class AB amplifier system includes a first Class AB amplifier circuit configured to receive an input signal. A bias circuit is configured to receive an output of the first Class AB amplifier circuit. A second Class AB amplifier circuit is in communication with the bias circuit. The second Class AB amplifier circuit is configured to generate an output signal. A current mirror circuit is arranged between the first Class AB amplifier circuit and the bias circuit. A common-mode feedback circuit is configured to generate a feedback signal based on the output signal.
