Hi i have an exponential cell having two transistors. I understand that best matching is to use common centroid or interdigitation and use a bulk ring around the two matched transistors but this is in the case if both the transistors share the same bulk like in a current mirror. But in my case A and B need matching but they have different bulk connections. So i only think i just can arrange the transistors in a proper matched way and not to use a bulk ring but use bulk separately on each transistor side. Can anyone tell if this is the right way to do it. Or any other good way to lay them out... Thank you!!!!
