ABSTRACT:
An amplifier includes: a class AB input stage, receiving an input signal, for generating an inner signal according to the input signal; class AB output stage, includes: a biasing circuit, for providing a first voltage and a second voltage according to the inner signal; and an output stage, for generating an output signal according to the first voltage and the second voltage; wherein a voltage difference between the first voltage and the second voltage generated by the biasing circuit is corresponding to the input signal.
