Hi there,
I have to size the simple two-stage opamp (see picture) using the gm/Id methodology. But, every source which I checked, describes one transistor... I understand firstly u have to choose working points on these grapes, but how does it work for a system of transistors(like an opamp).
Honestly, I don't have time for going throw every point, maybe someone here have a perfect and easy solution how to size a two-stage opamp with gm/id?
really need help,
Best,
Alex
