Re: Random thoughts on sinewave oscillators

Is the reason why this doesn't produce a better looking sinewave because
the amplifier slew rate is faster going down than it is going up or some
other reason?
 
Ignore the wild decoupling, it took me long enough to get the concept to
work at all.
 
I'm aware that a single package containing two op amps could probably do a
much better job.

if noise is more important than waveform, I found amplitude control by
clipping gave the lowest noise.  The oscillators in this...
