 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.
