| Ideally the collector of PNP Q<sub>3</sub> would be connected to some negative voltage with respect to ground. Try connecting the collector of Q<sub>3</sub> to the negative board supply Vn. What happens? Can the input node of the mirror get even closer to ground now? | Ideally the collector of PNP Q<sub>3</sub> would be connected to some negative voltage with respect to ground.
