LOGO复合管OTL功放实用电路第六章第三节复 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、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 ）=12Hot TipvHow do I incorporate my logo to a slide that will apply to all the other slides?
