In this circuit, if a resistor of 1 M\$\Omega\$ is connected between A and B, what is the effect on the stability of the quiescent point?
The analysis I made led me to believe it would provide positive feedback and thus won't stabilize the point, but I dont feel safe enough as to assure it. Which is a good method for verifying this? I couldn't think of a way to check it in a circuit simulation
