Description: 
"互補(bǔ)推挽輸出級(jí)電路圖" 
"	這種電路廣泛應(yīng)用于功率輸出級(jí)和集成運(yùn)算放大器的輸出電路中。" 
"	圖中VT1和VT2組成推挽輸出級(jí)，VT3是推動(dòng)級(jí)。推動(dòng)級(jí)以電流源作為有源負(fù)載。二極管D1和D2用來(lái)使輸出級(jí)兩管取得合適的偏置。這里用二極管而不用電阻，是因?yàn)槎O管的微變電阻比直流電阻小，可以使VT1和VT2的基極間保持必需的直流電位差，而交流電壓降很小，這樣VT1和VT2得到非常接近的交流電壓，從而能在負(fù)載RL上得到正負(fù)兩半周對(duì)稱(chēng)的波形。" 
"	由于VT1和VT2具有相反的導(dǎo)電型，在相同輸入信號(hào)作用下，其電流的大小變化方向相反，一個(gè)管的電流增大時(shí)，另一個(gè)管的電流減小。流過(guò)負(fù)載的電流是兩管電流之和，其總效果可形象地喻為一推一挽，互為補(bǔ)充，這就是此一電流被稱(chēng)為互補(bǔ)推挽電流的由來(lái)。"
