Follower circuit structure with built-in negative feedback

The invention discloses a follower circuit structure with built-in negative feedback. An amplification unit is added on the basis of an existing follower circuit. The output of the amplifying unit controls the current load of the follower circuit to form a built-in negative feedback loop, so that the output bandwidth and the conduction function of the frequency domain of the follower circuit can be adjusted, and the output current of the follower circuit can be adjusted, thereby improving the dynamic driving capability of the follower circuit. Compared with an existing follower circuit, on thebasis that few devices are added, the time domain and frequency domain characteristics of the follower circuit are greatly improved, and the advantages are obvious. 本发明公开了一种带内置负反馈的跟随器电路结构，通过在现有跟随器电路的基础上增加放大单元，放大单元的输出再去控制跟随器电路的电流负载，构成内置负反馈环路，可以调整跟随器电路的输出带宽、频域的传导函数，同时可以调整跟随器电路的输出电流，从而提高跟随器电路的动态驱动能力。且相对于现有跟随器电路，本发明在增加很少器件的基础上，极大的提升了跟随器电路的时域和频域的特性，优势明显。
