The output swing can be improved efficiently with push-pull class-AB outputstage, thus high-drive capability with low power supply is obtained.
输出级采用推挽式AB类结构，能有效地提高输出电压的摆幅，从而得到电路在低电源电压下的高驱动能力。

When designing outputstage, in order to enhance the efficiency, it uses the push-pull common source stage amplifier as the output stage, the output voltage swing basically reached rail-to-rail.
在输出级设计时，为了提高效率，采用了推挽共源级放大器作为输出级，输出电压摆幅基本上达到了轨至轨；

Second, a push-pull class A amplifier outputstage will have inherent rejection of power supply ripple and noise.
