bandgab 稳定性的仿真问题

急啊。

我注意了了正反馈小于负反馈。但整个系统的稳定性，怎么去仿真啊。同志们，救命啊。

哎，怎么没有热心人呢，是不是太简单了。

try a VDD step and see if the Vref oscillate in .tran

i have done that,and have not problems from it.
but how i simulate the system's PM,thank you.

In my opinion, it's no need to have AC simulation of the system.
If your opamp's PM is enough, the system would bestable

opa's PM its own.
i think the system's simulation is enough..

详细得bandgap仿真很多项目了
环路稳定性，打断一处加AC信号
其实还有很多上电，复位，噪声，psrr，之类得

恩，你说的很全面
