Hey all. I have a question regarding an equation in a document I am reading about convex optimization of OP-AMPs. The document is attached, the equation is of section 3.4 and the equation number is (9). Can you please explain how it came to be? I understand that i3 = i4 = i5/2 but I don't understand why W's and L's are the only thing in this equation and why this equality holds.(adsbygoogle = window.adsbygoogle || []).push({});

An explanation for equation (10) would also be nice, but (9) is more important for me!

Thank you for your time.
