Hi guys,
can any1 of you explain how to use gm/id charts (it took me like 3 days to even get them and now I can't use them.... it's kinda sad :-()? I've been looking for easy explanations but haven't found them.
If I want to build an OTA like shown in the picture with the following specs: open loop gain = 70dB, GBW = 16 MHz, 0.18 µm technology... how do I proceed? Right now I feel like randomly choosing positions in that charts but that can't be it, can it?
Well, actually I don't know how to start that at all... pls help me,
Winny
 

In this book you can find detailed design info, gm/id charts and calculation examples for three different OTAs (re. noise & speed) using this design methodology.
