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?  :sweat:  :) ) 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')



Audio must be the only branch of engineering where lack of basics' knowledge is considered a superior form of wisdom. (Anon)

Yowza, this is intense!

I also find myself going back to these two articles on opamp comparisons as well. Might be useful for others:
