Current-Voltage feedback, you can conduct the output resistance using feedback theory, it's make sense to understand the feedback effect, such as increasing output resistance for current -voltage feed ...
Thank you for your kindly reply.
So the current feedback at output node make the rout of this circuit much bigger , in fact multiplyed by gm*Rs |
