The main disadvantage of push-pull class A amplification over single-ended class A, is the necessity for a phase splitter stage to generate the oppositely-phased drive signals. 的主要缺点推挽放大了A类单端A类,是有必要的一个阶段分流阶段产生相反相驱动信号。
Second, a push-pull class A amplifier output stage will have inherent rejection of power supply ripple and noise. 第二,推挽A级放大器输出阶段将拥有固有拒绝电源纹波和噪声。
When designing output stage, 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;
The output swing can be improved efficiently with push-pull class-AB output stage, 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。
The circuit was based on CMOS reference operating in subthreshold region, using PMOS differential input and push-pull CMOS output stage mode. 该放大器利用工作在亚阈值区的CMOS基准源,在此基础上运用了PMOS差分输入级,以及CMOS推挽输出级结构。
