WOW!!Thanks Nidri!
Having perused this for the last 90 minutes ....... giving a barely possible 'feel' for all this work .....
This is massive; would have liked to know how long it took the author (plus a few attendants?

) In particular the summing (p 421 - 429) should be of great interest/informing-value for those of us not using op-amps regularly.
For me, even at this late stage in my life, I am definitely going to try to get a copy - although reading on-line would probably suffice for the once-off user. (I am going to also announce this on 'General', just in case some miss it on 'DIY')
