I am learning current mirrors. I have a curious doubt. Why is there a need to increase the Rout of a setup to improve the performance of current mirror? Ie. How is Rout and performance of a current mirror related? After all, the reference Ids current on the 1st transistor is copied to the second transistor's output making both those Ids currents of those transistors equal right? Why is improvement of Rout involved in this?
