感谢WeekendLabs截图分享....https://space.bilibili.com/441009203
结构:
输入:差分放大电路--差动(抗共模)
高增益放大
达林顿管---复合管
互补输出电路
Vbe倍增电路
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
负反馈:满足虚短、虚断
正反馈:（是不满足虚短、虚断）---滞回比较器
电压跟随器:输出纯净的电压信号
