The subject matter is mainstream science. Unconvinced? Go take a leap.

Duane went home yesterday, started chemo today. Now asking my wife/his mother to make all the home-cooked things... real beef burritos, etc ;-) ...Jim Thompson -- | James E.Thompson, P.E. | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona Voice:(480)460-2350 | | | E-mail Address at Website Fax:(480)460-2142 | Brass Rat | | http://www.analog-innovations.com | 1962 | I love to cook with wine.

I don't like railing U5, because it may do funny things to the delay around the loop, and waste power... some opamps get weird when you do this. And the diode hard clipping creates more distortion than you'd get if you soft-clipped the tops of the feedback but left it sorta sinusoidal. I'd expect that you might get more distortion, especially 2nd harmonic, in real life, as compared to the sim. You did ask. I should post my 1-transistor, low-distortion, super-amplitude-stable oscillator, which I did as a kid, for the Boresight Alignment System on the C-5A. John
