In a conventional bandgap, Point B is connected to the negative input of opamp while Point A is connected to the positive input of opamp.

My question is if the inputs of opamp is reversed, B to positive and A to negative, Is there any difference between this configuration and the former one ?

best regards,
and thanks
 

it will be unstable, because there is a positive closed loop in you circuit according to what you say
