Abstract:
A multi-stage Class AB amplifier system comprises a first Class AB amplifier circuit that receives an input signal. A bias circuit receives an output of the first Class AB amplifier circuit. A second Class AB amplifier circuit having an input that communicates with an output of the bias circuit and that generates an output signal. A common-mode feedback circuit generates a feedback signal to the first Class AB amplifier circuit based on the output signal.
