hello every one ..im doing a brokaw bandgap and using an ideal vcvs to simulate .. i get excellent result but everything gets worth when using an actual opamp .. what can i do ?

I think you should set a reasonable gain of ideal vcvs ,then you design an actual opamp .The gain of the opamp >60dB at least.

注意loop极性，是不是正反馈了。
