Here's a draft of the first 5 pages of a 6-page section I'm finishing. This is the last section to go into the x-Chapters book. Everything is down to the wire, and there isn't time for all the feedback I'd like. But we still have a few more days to fix errors, clarify things, etc.
(Also recall our earlier s.e.d. discussion: "op-amp-controlled MOSFET cucrrent-source, example")
