Abstract:
A multi-stage Class AB amplifier system comprises a first Class AB amplifier circuit (20) that receives an input signal. A bias circuit (24) receives an output of the first Class AB amplifier circuit (20). A second Class AB amplifier circuit (28) communicates with the bias circuit (24) and generates an output signal. A common-mode feedback circuit (30) generates a feedback signal based on the output signal.
