Hi everybody,

I'm analyzing the MOSFET Cascode current mirror structure, with focus on the mirroring error due to the channel modulation.

I actually know the result but I can't demonstrate it, can you help me?

The mirror I'm talking about is the one on the right


Considering the early effect, I0 should be



Thanks in advance
