Also input and output refers to the direction of a signal flow. So your "wrongly" remembered gm can be correct depending on the circuit!!! Bimpelrekkie Bimpelrekkie So, a signal can flow into the output of a transistor?

Why does it make sense to even call it the "output" then? It is a bit confusing. I haven't studied current mirror till now though, so I don't really know. The wire can have a conductance or resistance.

Transconductance is related the voltage between two nodes to the current through two other nodes. If I make gm large enough that R will approach zero and behave as a wire assuming an ideal transconductance. To be a trans conductance it has to transfer the conductance from one port to the other.
