I would have, but I downloaded the article that triggered my interest it from Electronics Design News some months ago, and I can't now find it in the EDN articles. In the article is a reference to page 236 of 'Analog Circuits - World Class Designs', edited by BP, but this doesn't address varying R2 over a wide range of tuning. However, it does say that varying R2 doesn't change the peak frequency gain, and that gain is R3/2R1.

Would you please supply the original article, chapter or whatever in which Bob Pease wrote his result? Thank you.

I have uploaded the above as a .ZIP. According to Bob Pease, the gain at the peak should be close to 34 dB, independent of the tuned frequency. I don't get either of those results using version 24.1.8. However, the bandwidth is fairly constant with frequency, as predicted. I can't believe Bob Pease reported the performance in error.
