推挽放大器

现在，你可能会想，怎么能推挽放大器是A类？

Now , you might be thinking , how can a push-pull amplifier be class A ?

巴伦（balancedtounbalancedtransformer，Balun）是平衡非平衡转换器的英文翻译，在微波平衡混频器、倍频器、推挽放大器和天线等设备中得到广泛应用。

Balun ( balanced to unbalanced transformer , Balun ) is the abbreviation of the balanced to unbalanced transformer and has already been widely used in many fields such as balanced mixers , frequency multipliers , push-pull amplifiers and antenna feed networks .

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。

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

一个单端A类放大器的输出变压器是巨大相比，推挽A级放大器相同的功率水平。

A single-ended class A amplifier output transformer is huge compared to a push-pull class A amplifier of the same power level .

设计了一种高线性度的宽带CMOS全差分放大器，输入级采用带有电阻共模负反馈的差分电路，输出级则由推挽跨导运算放大器及其反馈环路组成。

A highly linear CMOS wideband fully-differential amplifier is developed , the input stage is the basic differential pair with resistor common-mode feedback and the output stage consists of an push-pull OTA and its feedback network .

基于以上理论，分别选择了ZVS谐振型全桥串联逆变器、E类放大器以及推挽式E类放大器进行详细的理论分析，仿真比较以及小功率实验对照。

Grounding on above theory , the ZVS resonant of soft switch full-bridges circuit , and class-E amplifier , and push-pull class-E amplifier are analyzed respectively in theory .

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；

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 .
