Homework Statement



This is question 2.78 out of Sedra/Smith Micro electronics textbook. (6th edition)

Homework Equations





The Attempt at a Solution



I'm confused as to how the authour of my textbook draws this conclusion in his work. (I have it circled)

By the way, in the given question we are analysising the circuit in the figure to demonstrate how it is a voltage to current converter regardless of the value ZL.

Can someone explain?

I've posted an attachement of my work as well.

Thanks again!
