1、复合管OTL功放实用电路,第六章第三节,,Company Logo,复 合 管,复合管的定义：,将两只或两只以上的三极管的等效成一只三极管叫复合管，又称达林顿管,复合管产生的前提：,输出功率较大的功放管要使用大功率管，但大功率管的电流放大系数一般较小且不易配对，所以功放管通常采用复合管,,Company Logo,复 合 管,2、复合管等效三极管的类型与前一只三极管的类型一致（位置上）。,复合管的复合原则：,1、复合管内每只三极管的各极电流方向正确且互不抵触,,Company Logo,复 合 管,复合管的复合方法：,1、同种管型：前一只三极管的e极与后一只三极管的b极相连，c极直接相连,2、
2、不同管型：前一只三极管的e极与后一只三极管的c极相连，前一只三极管的c极与后一只三极管的b极相连,,Company Logo,复 合 管,复合管的电流放大倍数约为两只三极管放大倍数的乘积,减小穿透电流的方法：在后一只三极管的基极并联一只合适的电阻。（如下图）,=12,,Company Logo,Hot Tip,How do I incorporate my logo to a slide that will apply to all the other slides?
